The Qom Formation, a series of shales, sandstones and carbonate deposits, is the last transgression of the sea in Central Iran sedimentary basin. Foraminifera are one of the most important and numerous fossil groups present in the Qom Formation. In this study, the micropaleontology of the Qom Formation in three measured stratigraphic sections in south and west of Tafresh (Rakin, Band-e-Ali Nagh...

This paper shows the main results of a multidisciplinary study performed along southeastern sector Agri Valley in Basilicata (Southern Italy), where Cenozoic units, crucial for constraining progressive evolution Southern Apennine thrust and fold belt and, more general, geodynamic Mediterranean area are widely exposed. In particular, we aimed at understanding stratigraphic tectonic setting deep-...

S U M M A R Y Geophysical inversion is often ill-posed because of inaccurate and insufficient data. Regularization is often applied to the inversion problem to obtain a stable solution by imposing additional constraints on the model. Common regularization schemes impose isotropic smoothness on solutions and may have difficulties in obtaining geologically reasonable models that are often suppose...

The Central Balkan Zone belongs to the north-vergent fold-and-thrust belt of Alpine orogen. In this zone, pre-Permian low-grade rocks, metamorphosed during Variscan orogeny, were later reworked at two main stages compressional tectonics. Several tectono-stratigraphic subdivisions these metamorphic rocks previously presented, based on a purely stratigraphic approach in absence detailed structura...

Abstract In the design and construction of buildings infrastructures, reconstruction a reliable 3D engineering geological model is an essential step to optimize costs limit risks from failure or damage due unforeseen ground conditions. The modeling conditions challenging issue be tackled especially in case units with complex geometries spatially variable geotechnical properties. such direction,...

Soil-geomorphic studies indicate that six major allostratigraphic units occur in Crater Flat, Nevada, adjacent to Yucca Mountain. These units are, from youngest to oldest, Crater Flat, Little Cones, Late Black Cone, Early Black Cone, Yucca, and Solitario. Presence and degree of differentiation of Av, Ak, Bw, Bt, Btk, Btkq, and Bqkm genetic soil horizons characterize units, confirm relative ages...
