Volcaniclastic sedimentary rocks bounding the Ordovician Garth Tuff in North Wales were deposited in a shallow marine setting adjacent to a magmatic arc. The volcaniclastic sedimentary rocks are primarily of angular to euhedral quartz, angular euhedral feldspar, and volcanic rock fragments. These grains...
The mantle is the origin of this rock type. Igneous rocks are either intrusive or extrusive. Extrusive igneous rocks come from the mantle and reach the earth's surface usually in a volcanic eruption. Intrusive igneous rocks also originate in the mantle but cool before they reach the surface. ...

In order to help unraveling the thermal history of Late Paleozoic sedimentary rocks in West Virginia, a rock magnetic study was conducted with a focus on the Marcellus Shales which are of interest for petroleum exploitation. Vitrinite reflectance, fluid inclusions microthermometry data and conodont alt...
Most of the organic matter is buried in clay that is slowly converted to a fine-grained sedimentary rock known as shale. During this conversion, organic compounds are transformed to oil and natural gas. Sampling on the continental shelves and along the base of the continental slopes has shown ...

Each province has its own geological and sedimentary history. The structural development of the Bengal Basin began during the Early Cretaceous, when the Gondwanaland continent was rifted, from a regional perspective. During the Late Cretaceous-Late Eocene, the Indian plate drifted and collided with ...
