Low-latitude continental shelves, mixed siliciclastic–carbonate sedimentary systems, provide an understanding of sedimentary environments driven by paleoclimatological processes. The Bonaparte Gulf, northwestern Australian continental shelf, is among the widest in the world, ranging to 500 km, with shallow carbonate terraces and platforms that were exposed during periods of lower sea level. The...

Radiocarbon dating of Arctic marine sediment is often challenging due to the low availability calcareous fossils. Consequently, bulk organic matter has at times been used establish core chronologies. Yet, radiocarbon dates based on appear deviate vastly from fossils, mainly caused by input allochthounous carbon, including terrigenous matter. In this study, we aim examine link between compositio...

introduction hornblende-bearing gabbroic rocks are quite common in subduction-related magmatic suites and considered to represent magmatic differentiation process in arc magmas (heliker, 1995; hickey-vargas et al., 1995; mandal and ray, 2012). the presence of hornblende as an important mineral phase in gabbroic rocks of subduction zone has been considered either as an early crystallizing minera...
