Age and correlation of volcanism in central Livingston Island, South Shetland Islands: K-Ar and geochemical constraints

first_imgVolcanic sequences in central Livingston Island can be divided into two broad groups. The older group consists of basalt-dacite lavas, clastic rocks and associated hypabyssal intrusions. The lavas are lithologically and compositionally similar to other pre-Pliocene, volcanic arc lavas in the South Shetland Islands. The outcrops vary from relatively fresh (at Cape Shirreff, Hannah Point and Siddons Point) to indurated and pervasively altered (at Mount Bowles, Burdick Peak and Hurd Peninsula). Samples from the fresh outcrops yielded Late Cretaceous ages for eruption or intrusion, ranging from 90.2 ± 5.6 Ma at Cape Shirreff, to 73.0 ± 2.3 at Siddons Point. Chemical analyses of the lavas suggest that the sequences at these two outcrops can probably be correlated stratigraphically with the Byers Group and Coppermine Formation, respectively. Two samples from Hannah Point yielded conflicting ages of 87.9 ± 2.6 Ma and 67.5 ± 2.5 Ma from the centre and top of the sequence, respectively. The stratigraphical affinities of the Hannah Point sequence cannot yet be determined unambiguously but it is unlikely to be part of the Byers Group. All of the samples from the altered outcrops (which correspond to the Mount Bowles Formation) yielded Eocene-Oligocene K-Ar ages (44.4 to 35.0 Ma), interpreted as reset ages related to the emplacement and cooling of a nearby Eocene tonalite pluton responsible for much of the alteration, and also dated in this study (43.3 ± 2.8 Ma). A Cretaceous eruptive age (possibly Late Cretaceous) for the altered outcrops is likely but cannot yet be proven. By contrast, the younger group consists of degraded basalt lava flows, tuff cone and tuff ring remnants, which are part of the Inott Point Formation. The lavas are very fresh and Pleistocene or Recent in age (≤ 1 Ma). They are compositionally distinctive and are indistinguishable from supra-subduction alkali basalts preserved elsewhere in Livingston, Greenwich and Penguin islands.last_img read more

Obermeyer, age 94 of Batesville, died Monday, January 7, 2019 at Margaret Mary Health.  Born March 2, 1924 in Ripley County Indiana, she is the daughter of Catherine (Nee: Bruns) and Edward Prickel.  She married Joseph Obermeyer and he preceded her in death October 19, 2002.  Alma was a homemaker and a member of Holy Family Church in Oldenburg.A devout person, her faith and her family were most important to Alma.  She enjoyed providing for her family and being an excellent cook, she loved cooking for them.  Her roast beef was absolutely delicious and although she shared the recipe with others, they feel she left out an ingredient or two, because theirs just doesn’t taste quite as good.  She was also a good baker with the irony being she herself was not a big desert eater.  At 94, Alma remained active, driving and exercising right up to her death, which was good because according to her family she loved to go shopping.  She also put out a garden yearly, canning and freezing the excess.  Alma always wore a smile and her family described her as a grand lady who was emotionally and physically strong.She is survived by her son and daughter-in-law Mel and Deb Obermeyer of Batesville; grandsons Dr. Doug (Sarah) Obermeyer and Nick (Tara) Obermeyer, all of Batesville; step grandsons John (Holly) Williams of Villa Hills, Kentucky, Jason Williams of Finley, Ohio, Jared (Natalie) Williams of Loveland, Ohio; five great grandchildren and four step great grandchildren.  In addition to her husband and parents, she is also preceded in death by brothers Alanus “Doc” and Albert Prickel.Visitation is Wednesday, January 9th, from 9 – 11 a.m. at the Weigel Funeral Home.  Funeral services will follow at 11:30 a.m. at the Srs. of St. Francis Chapel due to renovations being done at Holy Family Church and burial will be in the church cemetery.  The family requests memorials to the Summer Food for Kids Program.last_img read more


Irvine open to Ideye talks

first_img The striker was left out of the squad for the 1-0 win at Leicester on Saturday and has so far struggled for form and fitness. He has netted once since his record-breaking Baggies move from Dynamo Kiev in the summer, in the 3-2 Capital One Cup win over Hull in September. West Brom head coach Alan Irvine has left the door open for record-signing Brown Ideye after he axed the £10million man. The Nigeria international picked up an ankle injury in the process but has since recovered and Irvine is happy to speak to Ideye if the forward so wishes. Irvine said: “The way that we do it is I say to any player ‘If you want to come in on Monday, come in on Monday’. “But when the team’s named and the subs are named they have to accept that, respect the rest of the players and then come back in later if they want to have a chat. “I might have a chat with him if he feels he needs to have a chat, but if he doesn’t then I won’t be calling him in.” Ideye has made just two starts in the Barclays Premier League this season and has made little impact at The Hawthorns. Irvine said his omission was purely for tactical reasons as he picked Victor Anichebe and Georgios Samaras on the bench at the King Power Stadium. “I haven’t had a chat with him. We pick the team carefully even if it’s the same team. It’s still chosen with a lot of thought and care – that applies to the subs as well,” he told the Wolverhampton Express & Star. “What we knew was that Leicester had a physical presence. Generally, I have two centre-forwards on the bench. “I decided that I needed physical options there rather than somebody like Brown – whose strengths are running in behind. That’s why I went for Victor and Sami (Samaras).” center_img Press Associationlast_img read more


Lorenz’s switch score for soccer

first_imgGREG DIXON/Herald photoAt this time last year, Scott Lorenz’s job was to prevent goals, not score them. As the left back for the UW men’s soccer team, Lorenz found far more opportunities to block shots than to take them.Fast forward to 2008, and Lorenz, a junior, leads the team with 21 points off of nine goals and three assists after tallying only five points last year. There’s a reason for the dramatic increase.“He’s playing forward instead of defender,” head coach Jeff Rohrman said. “We saw signs of what he could do last spring as a forward. It’s not a position he’s completely unfamiliar with.”“Not unfamiliar with” is a bit modest. Lorenz was an All-State forward at Barrington High School in Illinois, scoring 19 goals his senior year. Upon arriving at UW, he was asked to step in and fill a hole the team had on defense, and in Rohrman’s words, “adjusted well.” When the team’s need shifted back to offense, the coaching staff let Lorenz slide back to his natural position. And the readjustment hasn’t been an issue, as evidenced by his performance on the field.“It’s nice. It kind of gets me back to what I’m used to doing,” Lorenz said. “It’s pretty much like riding a bicycle. It just comes back to you.”During the spring offseason, Lorenz was called on to see if he could bring a scoring touch to the offense. He’s responded by leading the team not only in goals, but also in shots and minutes played. Thirty-three of his 57 shots have been on goal, a .579 clip that leads the team among players with at least five shots. To Lorenz, the motivation to take quality shots is simple.“You can’t score if your shots aren’t on target,” Lorenz said. “Sometimes you have to take a little off the shot to become more accurate and take that chance better than maybe just bombing away at it. … If you get it on target, maybe something good will happen, maybe the keeper will drop it or something like that.”The “shooting on target” mantra has worked so far, but more importantly, it’s worked when it mattered most. Five of Lorenz’s goals have either won or tied the game; he leads the team with three game-winners and is tied for first with two equalizers. With as much trouble as the Badgers have had offensively at times this season, Lorenz’s performances in the clutch have not gone unappreciated.“It’s been great for us,” Rohrman said of Lorenz’s timely scoring. “It’s nice in tight games and against good opposition when you have players step up and accept that responsibility, to take it on and make something happen.”Lorenz’s success comes as no surprise to Rohrman. Lorenz has the size and speed to complement his good sense for the game.“The things Scotty brings that make him one of the more dangerous players, is he’s able to convert things with his feet, with his head,” Rohrman said. “He’s got great agility, balance and athleticism that allows him to free himself up to get … into positions to score.”As Rohrman said, it’s certainly helped that Lorenz is supported by players like recent Big Ten player of the week Victor Diaz and former midfielder Brandon Miller, who joined Lorenz in the top 10 in conference scoring after moving to forward. And despite the individual success he’s had, Lorenz is the first to defer credit to his teammates.“I think they really balance me well and let me get in the right position to score,” Lorenz said. “It’s not so much me doing a lot of individual work as it is the team doing it and me being in the right spots. It’s really [something to] attribute to the rest of the team.”Rohrman believes Lorenz’s other strengths are things that aren’t reflected in box scores or leader boards.“The thing I appreciate as much as the other stuff is how he works and pressures on the defensive side,” Rohrman said. “That’s something that maybe goes unnoticed, and in a lot of ways, doesn’t get the recognition that goals and assists do. But nonetheless, it’s an important part of any team. When you have attacking players that are willing to do that stuff, it makes everyone else’s job easier.”Rohrman believes Lorenz’s competitive nature is the reason for his work on both sides of the ball. Lorenz places some of the blame on his time as a defender for putting the defensive aspect of forward into perspective.“[After] playing defense last year, playing offense, you don’t understand how much it helps the defense when you can put pressure on the ball and force turnovers in your offensive half,” Lorenz said.With the Big Ten Tournament looming, Lorenz is going to have to continue to perform if the Badgers are to find any success. Regardless of whether he’s putting the ball in the net or trying to lighten the load for his defense, Lorenz is going to be counted on to provide a spark for the team. To Rohrman, there’s no question that all the factors to make a difference are there.“I just think he’s an extremely competitive kid,” Rohrman said, “and is willing to do whatever it takes and work his tail off to get the results.”last_img read more
