The volcano is composed entirely of dacitic pyroclastic materials, lava domes and subordinate thick lava flows. Its activity is divided into two groups, Older (1.0-0.4 Ma) and Younger (0.4 Ma to ca. 17.000 yr B.P.). Chemical compositions of phenocrysts in the members of the Upper Tephra...
Outcrop Greenish, fine grained, hard, compact with pyroclastic, pillowed and varioloitic structure. Mostly carbonated. Fine grained, light green and highly foliated. Schistocity defined by orientation of chlorite and sericite. Carbonates and pyrite at places. Argillite–greywacke boundary grade into ...

To provide new insights into the origin and evolution of kimberlitic magmas with different diamond concentrations from the Arkhangelsk diamond province in north-western Russia, we examined the major- and trace-element compositions of ilmenite from diamondiferous kimberlite of the Grib pipe and diamond...
Mass flow deposits of pyroclastic debris commonly consist of two parts, a lower coarse-grained basal section and an upper finer-grained bedded section. Sub... J Stix - Earth-Science Reviews 被引量: 77发表: 1991年 Donor free radical explosive composition An improved explosive composition is discl...
The writing in carbonized Herculaneum scrolls, covered and preserved by the pyroclastic events of the Vesuvius in 79 AD, was recently revealed using X-ray phase-contrast tomography, without the need of unrolling the sensitive scrolls. Unfortunately, some of the text is difficult to read due to ...
