The tectonic significance of the Cabo Frio Tectonic Domain in the SE Brazilian margin: a Paleoproterozoic through Cretaceous saga of a reworked continental margin

Brazilian Journal of Geology
: The Cabo Frio Tectonic Domain is composed of a Paleoproterozoic basement tectonically interleaved with Neoproterozoic supracrustal rocks (Buzios-Palmital successions).

Correlation of the supracrustal complexes of the Small and Large Keivy, North-East of the Baltic Shield

Vestnik MGTU
The issue of correlation between the Small and Large Keivy sections is considered using a technique that includes searching for trends in partially ordered sets of random variables and assessing the degree of similarity/difference between rock ...

Contact Metamorphism in the Supracrustal Rocks of the Sukumaland Greenstone Belt in the North West Tanzania

Tanzania Journal of Science, 2011
Biotite-granite intrusions in meta-ironstones at Geita Hills and the Bukoli alkali-granite intrusion in metabasites at Mawemeru area produced heat that baked the respective country rocks through epidote-amphibolite- to amphibolite-facies. Critical and informative mineral assemblages in the metairostones of Geita Hills are garnet-grunerite-epidote ...

Early Archean granitoid gneisses and supracrustal enclaves of the southern Inukjuak domain, Québec (Canada)

, 2019
The Inukjuak domain in northern Québec is part of the Archean Minto Block in the northwestern Superior Province of Canada, and hosts numerous km-scale supracrustal enclaves within variably-deformed granitoid gneisses. The Eoarchean (ca.

Seismic anisotropy in siliciclastic reservoir rocks [PDF]

, 2006
The interpretation of geophysical field measurements of seismic anisotropy is presently limited by our knowledge of the controls of the elastic anisotropy of sedimentary rocks in the subsurface. Traditionally, laboratory ultrasonic velocity measurements
