2023, 42(5): 93-101. doi: 10.1007/s13131-022-2121-2
Abstract:
We report the mineralogy and geochemistry of hydrothermal sulphide from the crater of a volcanic high near 18°36.4′S of the Central Lau Spreading Center. During 1990s, that volcanic structure was reported active and sulphide samples were collected by...
Petrographical and mineral chemistry evidence to delineate the source/sources of the Central Indian Ocean Basin pumices
Niyati G. Kalangutkar, Sridhar D. Iyer
2023, 42(5): 102-116. doi: 10.1007/s13131-022-2062-9
Abstract:
We present data pertaining to mineral assemblages and composition of the Central Indian Ocean Basin (CIOB) pumices. Eight groups of pumices were identified considering the presence of phenocrysts of plagioclase, clinopyroxene, orthopyroxene, hornblen...
Geochemical characteristics of Sr isotopes in the LS33 drill core from the Qiongdongnan Basin, South China Sea, and their response to the uplift of the Tibetan Plateau
