Pseudotachylitic breccia from the Dhala impact structure, north-central India: Texture, mineralogy and geochemical characterization

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