Modeling postbreakup landscape development and denudational history across the southeast African (Drakensberg Escarpment) margin [PDF]

, 2002
We employ a numerical surface processes model to study the controls on postbreakup landscape development and denudational history of the southeast African margin.

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 405-426, March 2026.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

THE COMPOSITION AND RECONSTRUCTION OF THE SOURCE AREA FOR THE LATE PRECAMBRIAN TERRIGENOUS ROCKS OF THE OSELKOVAYA SERIES (BIRYUSA PRISAYANIE)

Геодинамика и тектонофизика, 2016
We present results from petrographic and lithogeochemical studies of the Late Precambrian terrigenous rocks (sandstones, gravelites, and aleuritic sandstones) from the Oselkovaya series of Prisayanie. The studies were conducted to reconstruct the primary

Rapid oxygen diffusion during high temperature alteration of zircon [PDF]

, 2018
The mineral zircon through its isotopic and elemental signatures comprises the greatest archive recording the evolution of Earth’s continental crust. Recognising primary from secondary zircon compositional signatures is thus important for the accurate ...

Low Water Content of the Lower Continental Crust Induced by Decompression Melting: Evidence From the Weichang Granulite Xenoliths in the Northern North China Craton

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract The water content of granulite xenoliths from the Cenozoic Weichang basalts in the northern North China Craton (NCC) is investigated to constrain the nature and evolution of the lower crust. Granulites are categorized into felsic and mafic groups, characterized by widely developed glass‐bearing sieve textures in their constituent minerals ...

Heat and Tectonics of the Canadian Cordillera From the Seismically Constrained Inversion of Gravity Data

Tectonics, Volume 45, Issue 2, February 2026.
Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

Stratigraphic and Structural Framework of Upper Middle Ordovician Rocks in the Head Lake-Burleigh Falls Area of South-Central Ontario [PDF]

, 1993
Field investigations in the Head Lake-Burleigh Falls area of south-central Ontario, that focused mainly on the Covey Hill(?), Shadow Lake, Gull River and Coboconk formations along the Paleozoic escarpment, provided clear evidence of faulting.

Exotic accessory minerals in layered chromitites of the Campo Formoso complex (Brazil) [PDF]

, 2006
The Campo Formoso stratiform intrusive complex, in Bahia State, Brazil, considered to be of Paleoproterozoic age, consists of a tabular body of ultramafic rocks about 40 km long and 100-1100 m wide.

Tectonic stress field and crustal strength of the central-southern Tanlu Fault Zone

Dizhi lixue xuebao
Significance  The accurate estimation of crustal strength—the capacity of the lithosphere to resist tectonic deformation—is fundamental to both seismic hazard assessment and geodynamic studies.
