pleistocene basaltic lava flows, consisting of trachybasalt and basaltic trachyandesite, cover an area north-northwest of shahre-babak in southeastern iran. the whole rock chemistry indicates that the lavas are dominantly alkaline and mildly calc-alkaline. variation diagrams of sio2 with major and trace elements are consistent with fractional crystallization processes involving olivine, pyroxen...

S U M M A R Y 2-D elastic finite element models of the recent stress field of Central Europe are built to evaluate the loads exerted on the continental boundary and the magnitude of tectonic stresses within the continental part of the plate. The models comprise 24 tectonic blocks (their stiffness is either constant throughout the model or varies from block to block), 16 fault zones and 12 geolo...

In two earlier papers (Wallace et al., 1983, 1985), we discussed the evidence for tectonic release from underground nuclear explosions on Pahute Mesa at the Nevada Test Site (NTS) as observed in long-period body waves. It has been shown for some time that the nonisotropic component of the surface waves from most of these events could be explained by an equivalent double-couple source; namely st...

Introduction: Dione (1124 km in diameter) is a mid-sized icy moon of Saturn which shows a wide range in tectonic features across its surface revealing an intense geologic history. With the two highly evolved satellites Enceladus und Titan, Dione forms a set of three satellites whose surfaces have been shaped by tectonic activity on a global, not only on regional scale. Tectonic forms on Dione w...

The Kermanshah ophiolite complex is a part of the Mediterranean–Zagros–Oman Tethyan ophiolites, located in the structural–tectonic zone of western Iran in the northern part of the Zagros main thrust. Doleritic sheeted dykes are well exposed within the ophiolite in the south of Sahneh. These dykes contain high MgO, Na2O, low TiO2 (2O5, and K2O contents, and high FeOt/MgO and LILE/HFSE ratios. Th...

This paper presents a mechanism for the large-scale tectonic change that accompanied Noah’s Flood. It assumes that the onset of the Flood only a few thousand years ago correlates with the notable stratigraphical and paleontological discontinuity of the Precambrian-Cambrian boundary. This implies that the geological history recorded in the rocks usually classified as Paleozoic and Mesozoic unfol...

Introduction: Planar deformation features (PDFs) in quartz are diagnostic impact evidence. Using light microscopy, it is often impossible to distinguish between PDFs and tectonic deformation lamellae. [1] showed that PDFs can be imaged using a cathodoluminescence (CL) detector in a scanning electron microscope (SEM) and that in SEM-CL images PDFs can be distinguished from tectonic microfracture...
