The phylogenetic analysis of the 16 recognized genera in the Bunocotylinae, based upon 30 morphological transformation series, produced 2 most parsimonious trees, each with a consistency index of 0.62. The monophyly of the group is supported by 6 synapomorphies. Ahemiurus, Aphanuroides, Aphanurus, Myosaccium, and Indoderogenes separate independently in the basal part of the tree. Saturnius and ...

During the Late Paleozoic to Cenozoic, with closure of Tethys oceans, East and/or Southeast Asia was amalgamated by individual blocks. In order understand Paleogeography Eastern Paleo-Tethys, a systematic UPb dating on 11 samples have conducted constrain age and provenance elements forming Ailaoshan-Song Ma mélange. These consist ophiolitic mélange zone (6 samples), sedimentary cover Indochina ...

The formation ages and tectonic features of the Bulunkuole Complex (BKC) is critical for understanding geological evolution western section West Kunlun Orogenic Belt (WKOB), they are also metallogenic background Taxkorgan Iron Belt. In this paper, we report new geochemical in situ zircon U–Pb isotopes data most southwestern iron-bearing BKC. petrography sedimentation BKC reveal that main part w...

The present work focuses on palaeogeographic reconstruction of shallow-water carbonate deposition in the Outer Western Carpathian Tethys. Platform deposits are preserved only as a component turbidites and olistostromes, reconstructions these platforms based clastic material redistributed into slopes deep basins occurring among nappes. Similar were also Tethys margins. These performed using glob...

For the first time, a coupled general circulation model with interactive and dynamical atmospheric, oceanic, and sea-ice components, is used to simulate an Eocene (∼50 Ma) “greenhouse”climate. We introduce efficient ocean spin-up methods for coupled paleoclimate modeling. Sea surface temperatures (SSTs) and salinities evolve unconstrained, producing the first proxy data-independent estimates fo...

[1] An approach for seismic tomography is presented which allows the parameterization to be refined during the inversion. The objective is to use the data to refine the mesh and the velocity model together, and hence both are considered part of the solution. Some simple rules are used to identify the volumes of a three-dimensional model in need of refinement. The self-adaptive parameterization ...

A section from the southern (Austro-Alpine Northern Calcareous Alps) margin of the Penninic Ocean in the NW Tethys realm of Late Campanian age is investigated stratigraphically. Plankton foraminifer and nannofossil biostratigraphy designate the presence of the Globotruncana ventricosa Zone and the Radotruncana (Globotruncanita) calcarata Zone, and standard nannofossil zones CC21-UC15cTP and CC2...

The organic carbon isotope (δ13Corg) curve for ~1.7-km-thick mid-Cretaceous strata of the Chaqiela section in Gamba area, southern Tibet is presented in this study. C-isotopic chemostratigraphic correlation combined with biostratigraphic constraints show that the Chaqiela section spans early Aptian through early Campanian period, and that almost all of the carbon cycle perturbations and Oceanic...
