Cenozoic Age Counterclockwise Rotation in the Northwest End of the Sierras Pampeanas, Argentina

Open Journal of Geology 2023年第5期13卷 345-383页

作者： Adolfo Antonio Gutiérrez Ricardo Mon Clara Eugenia Cisterna uwe Altenberger Ahmad Arnous Faculty of Natural Sciences and IML National University of Tucumán San Miguel de Tucumán Tucumán Province Argentina National Council for Scientific and Technical Research Buenos Aires Argentina Institute for Earth and Environmental Sciences Potsdam University Potsdam-Golm Germany

Investigations into the Andean orocline revealed a counterclockwise rotation of about 37° in the north and a clockwise rotation of about 29° in the south. This rotation would have started in the Eocene because the Nazca and South American plates converged. The transition zone between the Puna and the Sierras Pampeanas has a clockwise rotation pattern. Our new data show that the NE convergence of the Nazca and South American plates caused the counterclockwise rotation around the NW end of the Sierras Pampeanas. The temperature rise during a magmatic activity at 13 Ma would have favored a counterclockwise rotation of the mountain blocks of about 20° on a detachment zone within 10 to 15 km of depth. These range rotations generated local stress tensors trending NE and NW, facilitating the development of valleys, basins, mineralized dikes, mineral deposits, and alluvial fans separated from their origin. The Atajo fault shows both ductile and brittle characteristics. A mylonitic belt from the Sierra de Aconquija was juxtaposed on the rocks of the Ovejería Block and the Farallón Negro Volcanic Complex by reverse vertical displacement, and a dextral horizontal component of displacement resulted in curvatures that gave rise to pull-apart basins and step over features. The Santa Maria Valley, Campo del Arenal, Hualfín Valley, and Pipanaco salt flat most likely constituted a vast early Miocene basin rarely interrupted by low feature relief.

A New Fossil Termite (Isoptera,Stolotermitidae,Stolotermes) from the Early Miocene of Otago,New Zealand

引用

Acta Geologica Sinica(English Edition) 2010年第4期84卷 705-709页

作者： uwe KAULFUSS Anthony C.HARRIS Daphne E.LEE Department of Geology University of OtagoPO Box 56Dunedin 9054New Zealand Otago Museum PO Box 6202Dunedin 9059New Zealand

The forewing of a termite from Early Miocene lake sediments in Otago, southern New Zealand is figured and described. It exhibits the generic characters of the damp-wood termite Stolotermes Hagen, but differs from forewings of the known species in size and venation pattern and is described as Stolotermes kupe sp. nov. S. kupe represents the first confident record of fossil Stolotermitidae and extends the fossil record of the family back to the Early Miocene. It also is the first direct evidence of fossil Isoptera from New Zealand, though silicified termite faecal pellets, referable to Kalotermes brauni, have been previously described. S. kupe indicates that Stolotermitidae has been present in the Australasian region since at least the Early Miocene.

Posterior Mediastinal, Intraspinal, Intradural, Intramedullary Lipoma through a Kovalevsky Canal in the Thoracic Spine

引用

Chinese Medical Journal 2017年第22期130卷 2761-2762页

作者： Da-Jiang Ren uwe Max Mauer Ulrich Kunz Fang Li Tian-Sheng Sun Department of Orthopaedic PLA Army General Hospital Beijing 100700 China Department of Neurosurgery German Armed Forces Hospital UIm D-89070 Germany

Spinal lipomas are benign tumors that are usually divided into extradural and intradural types. In all, 60% are located intradurally and 40% are located extradurally. The most common spinal lipomas are known to be associated with dysraphism in the lumbosacral region. We present a rare case of a posterior mediastinal, intraspinal, intradural, intramedullary lipoma through a Kovalevsky canal combined with the thilure of multiple segments from T3 to T6 in the thoracic spine.
