Diapirs and their role in the localization of mineralization

International Geology Review, 1976
In the local and foreign literature on the structures of ore fields and deposits, there are very rarely examples of localization, of endogenic ores in diapiric structures. However, the role of the latter as ore-enclosing structures is, in our opinion, more significant than has been accepted at the present time. We are convinced of this from appropriate

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

Sedimentology, EarlyView.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Tourmaline records the hydrothermal events related to Zn-Pb mineralization around the Murguía diapir (Basque Cantabrian Basin, N Spain)

Geologica Acta, 2019
The chemical composition of tourmaline has been used as a host environment register as well as a potential exploration tool for mineral deposits. In this study, the textural and chemical composition of tourmalines associated with Zn-Pb mineralizations ...

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

Sedimentology, EarlyView.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Geodynamic Modeling With Uncertain Initial Geometries

Geochemistry, Geophysics, Geosystems, 2022
Geodynamic codes have become fast and efficient enough to facilitate sensitivity analysis of rheological parameters. With sufficient data, they can even be inverted for.

Multi‐proxy sequence stratigraphy of a mixed carbonate–siliciclastic shelf across the Jurassic–Cretaceous transition

The Depositional Record, Volume 12, Issue 4, September 2026.
An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

Study on the planar structure characteristics of mud diapirs in Rio del Rey basin , West Coast of Africa(非洲西海岸里奥-德雷盆地泥底辟平面地质结构特征研究)

Zhejiang Daxue xuebao. Lixue ban
The Rio del Rey basin, located in the eastern margin of the Niger Delta Basin in West Africa, develops large-scale mud diapirs. There are some disputes about the activity time and mechanism of the diapirs. Based on the detailed interpretation and mapping

Large (∼80 km) Shield Volcanoes on the Moon Possibly Fed by Shallow Magma Reservoirs

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Large shield volcanoes are among the most prominent volcanic structures on terrestrial bodies. The Moon, while volcanically very active in the past and hosting various volcanic features, seems to lack such large shield volcanoes. Here, we report the identification of two lunar volcanic domes (Prinz‐Harbinger and Theophilus) with diameters ...
