Microscopy Research and Technique, EarlyView.This study calculated the texture coefficient (TC) values of 20 different rock textures with magmatic, metamorphic, and sedimentary origins, which underwent image segmentation using a novel approach. ABSTRACT The texture coefficient (TC) is a critical parameter used to analyze the microstructural characteristics of rocks and predict their mechanical ...

Anisotropic Magnetic Susceptibility Measurements on a Phonolite and on a Folded Metamorphic Rock
, 1963 i A description of a method of measuring anisotropic magnetic susceptibility in rocks, based on an original method by Ising, is followed by the results of a series of measurements made on an intrusion, and on a metamorphosed sedimentary rock ...

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT Microplastics (MPs) are of increasing global concern for species inhabiting aquatic habitats. However, the mechanisms behind animal responses to MPs still require comprehensive exploration. Amphibians are the most threatened vertebrate group with most species having a complex life cycle, commonly with an aquatic larval stage.

II.—Irish Metamorphic Rocks [PDF]
Geological Magazine, 1886 The meeting of the British Association in Montreal gave different Irish geologists facilities for examining the Archæan rocks of Canada and the States, while since then they and also American geologists have had opportunities for studying the Irish Metamorphic rocks; it may therefore be allowable to give an epitome of our knowledge in regard to the ...

Journal of Quaternary Science, EarlyView.Abstract The high mountains of Taiwan provide a unique location for Quaternary palaeoclimate research in East Asia and the north‐western Pacific. This study applies geomorphological field mapping and rock surface exposure dating with paired (10Be/26Al) in situ‐produced terrestrial cosmogenic nuclides to identify and date glacial landforms and boulders ...

Pegmatites of Southern California [PDF]
, 1954 For many years the southern California region has attracted the attention of geologists interested in pegmatites and pegmatite deposits, largely because of the well-known gem and lithium occurrences in San Diego and Riverside Counties. These world-famous
