Pseudotachylitic breccia from the Dhala impact structure ...

Pseudotachylitic breccia (PTB) occurs in a drill core from the crater floor of the 11 km diameter, Proterozoic Dhala impact structure, India. PTBs were intersected in late Archean granitoids between 348.15 m and 502.55 m depth in the MCB-10 drill core from the center of the Dhala structure. The breccias comprise both cataclastic-matrix as well as melt breccias.

Geochemical characterization | SPE

Geochemistry is the study of the chemistry of the Earth and within solid bodies of the solar system, including the distribution, circulation and abundance of elements (and their ions and isotopes), molecules, minerals, rocks and fluids. For geochemists in the petroleum industry, source rock geochemistry is a major focus. Geochemical techniques can determine whether a given source rock is rich ...
