By-products from the dairy industry and mining activities represent a great environmental overload, which justify research for value-added reuse of these by-products (dairy sludge dacite rock powder). Dairy is generated at rate about 0.2–10 l per liter processed milk, powder, extraction processing, 52,400 m3 year in Nova Prata city, Southern Brazil. For both by-products, compositions calcium (C...

The volcanic rocks in Semporna Peninsula, Sabah, Malaysia forms parts of the Miocene subjected slab during Miocene-Pliocene orogeny. This study presents new petrographic and geochemical data area. range composition from basaltic andesite, dacite to rhyolite, with most shows calc-alkaline affinity a minor tholeiitic feature. trace elements enrichment large-ion lithophile (LILE) light rare earth ...

The volcanic rocks of the Kaban dacite, which is subject study, are located in Olur (Erzurum) region eastern Sakarya zone. This zone divided into four tectonic slices as Hopa-Borçka zone, Artvin Yusufeli Tortum and Erzurum Kars Ophiolite from north to south, east Eastern pontides, investigated within Olur-Tortum These represented by dacites rhyolites study area. Petrographically, it observed fi...

sakhtehesar mountain is located in urumieh-dokhtar magmatic belt and is composed of volcanic and subvolcanic rocks (pliocene andesite to dacite) which intruded the volcanics and pyroclastics of paleocene age. three alteration zones including potassic, phyllic and propylitic are recognized in the area. in this paper, the mineral chemistry of magmatic and primary biotite and the mineral chemistry...

Abstract The last four caldera-forming ignimbrites in the central San Juan caldera cluster, Colorado, erupted 1400 km3 ≤80 kyr and alternated between zoned crystal-poor rhyolite to crystal-rich dacite unzoned, dacite. 150 Rat Creek Tuff (26·91 Ma), unzoned 250 Cebolla Tuff, 500 Nelson Mountain (26·90 Ma) formed nested Luis complex with slightly offset calderas, Snowshoe (26·87 Creede south. hav...
