Remagnetization of Lower Cretaceous Limestones in the Western Tethyan Himalaya and Its Tectonic Implications for the India‐Asia Collision

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 tracks and HS2: a twenty‐first century journey

Geology Today, Volume 41, Issue 6, Page 234-243, November/December 2025.
The biggest UK railway construction site since the nineteenth century has exposed a near‐complete time slice through the entire Jurassic succession of central England. This is yielding a wealth of stratigraphical, palaeobiological and palaeoenvironmental data that is otherwise generally poorly exposed at the present day.

Glimpses of ammonite lives

Geology Today, Volume 41, Issue 6, Page 260-268, November/December 2025.
Ammonites were molluscs, now extinct, that abounded in Mesozoic seas. Their external shells are almost always the only parts of them that are preserved, and their soft‐part anatomy and lifestyles remain largely unknown. The shells, however, can be preserved in various ways that shed light on the animals as living organisms, including their variation ...

DOCUMENTATION AND SIGNIFICANCE OF TECTONIC EVENTS IN THE NORTHERN TABAS BLOCK (EAST-CENTRAL IRAN) DURING THE MIDDLE AND LATE JURASSIC

Rivista Italiana di Paleontologia e Stratigrafia, 2004
Apart from global sea-level fluctuations, the sedimentary pattern of the northern Tabas Block during the Middle and Late Jurassic was mainly governed by tectonic events of varying intensity and areal extent.

Carbonate microfacies and transgressive‐regressive sequences of Oxfordian shallow‐water limestones (Korallenoolith, Lower Saxony Basin)

The Depositional Record, Volume 11, Issue 4, Page 1084-1106, September 2025.
The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.
