The Taku Schist, which is located in the north-east Peninsular Malaysia, characterized by its North-South oriented elongated body. It forms part of Indonesian orogenic build-up that was generated via convergence Sibumasu continental unit and Sukhothai Arc. Subsequent petrography analyses metasedimentary rocks sourced from Schist revealed their formation attributable to metamorphism greenschist ...

This study concerns the lithologic characteristics of stone used as main construction materials ancient Korean tombs, and aims to understand how they were supplied. Specifically, we investigated tombs in Songpa district, south Hangang River Seoul, composing connected stone-mound Seokchon-dong tomb complex, Bangi-dong No. 3, 13 horizontal stone-chamber Gamil-dong complex. There are major differe...

, ABSTRACT Metabasaltic rocks in the Klamath Mountains of California with 'komatiitic' major element concentrations were investigated in order to elucidate the origin of the magnesian signature. Trace-element concentrations preserve relict igneous trends and suggest that the rocks are not komatiitic basalts, but im~at~re arc rocks and within-plate alkalic lavas. Correlation of 'excess' MgO with...

U.S. Department of the Interior U.S. Geological Survey Wheeler Geologic Monument (Half Moon Pass quadrangle) provides exceptional exposures of three outflow tuff sheets erupted from the San Luis caldera complex. Lowest sheet is Rat Creek Tuff, which is nonwelded throughout but grades upward from light-tan rhyolite (~74% SiO 2 ) into pale brown dacite (~66% SiO 2 ) that contains sparse dark-brow...

Abstract Water supply deficits in droughts, groundwater pollution and climate change are the main challenges for sustainability of resources from hard-rock aquifers rural areas Galicia (Spain). Here, we address weathered fractured schists Abegondo municipality. The conceptualization hydrogeology study area includes: (1) schist (regolith), (2) decompressed highly layer; (3) An underlying slightl...

Cutts et al. (2014) combined thermodynamic modeling of compositional change in metamorphic garnet with metamorphic peak and retrograde pressure-temperature (P-T ) data derived from quantitative P-T pseudosections to determine clockwise P-T paths for several samples from the Tjakastad schist belt. The Tjakastad schist belt is located in the central portion of the Stolzburg domain at the southwes...

Greenschist facies metabasite (chlorite schist) and metasediments (banded iron formation (BIF)) in the Wutai Complex, North China Craton recorded extensive fluid activities during subduction-related metamorphism. The pervasive dolomitization chlorite schist significant dolomite enrichment at BIF–chlorite interface support existence of highly channelized updip transportation CO2-rich hydrotherma...
