Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.Abstract The drift history of the Tethyan Himalaya provides key constraints on the India‐Asia collision, Himalayan‐Tibetan orogenesis, and associated global climate change. Here we present rock magnetic, petrographic, geochronologic, and paleomagnetic results of the Bolinxiala Formation limestones in the western Tethyan Himalaya.

Jurassic jeopardy—life and death on an ancient seafloor
Geology Today, Volume 41, Issue 6, Page 244-250, November/December 2025.The Lower Jurassic Down Cliff Sand Member of the Dorset coast, southern England, is a rich source of marine invertebrate fossils. Among these are echinoderms and less common arthropods. Despite having multi‐component skeletons that are prone to disarticulation, remains of some of these are remarkably complete.
