Jakarta has been experiencing severe land subsidence over the last few decades. A questionnaire survey of local inhabitants revealed that seawater is already overtopping coastal dykes and flooding a vulnerable community along Jakarta’s waterfront. The present study projects coastal floods around Jakarta until the year 2050 to understand the long term effectiveness of proposed dykes under contin...

Melting of mafic veins in a marble-cake mantle may play an important role in generating isotopic and chemical heterogeneities in mid-ocean ridge and ocean island basalts. Mafic veins have lower solidi than mantle peridotite and will be preferentially sampled during partial melting, particularly at low melt fractions. However, the abundance of mafic components in the mantle or their role during ...

Hafnium and neodymium isotopes provide robust tool tracers for tracking the mechanisms of crustal generation differentiation, from mantle extraction to late geological processes undergone by studied rocks. Though these two isotope systems commonly behave similarly define a positive correlation between 143Nd/144Nd 176Hf/177Hf referred as “terrestrial array”, they may differ in terrains having co...

The Ottfjället Dyke Swarm (ODS) is a prominent component of the Ediacaran mafic magmatism associated with opening Iapetus ocean, and hosted in Särv Nappe, Middle Allochthon Scandinavian Caledonides. A U-Pb baddeleyite age 596.3 ± 1.5 Ma for thick, well preserved, plagioclase-phyric dolerite dyke Härjedalen, Sweden, dates emplacement swarm. represents robust, inheritance-free reference variably ...

Mafic enclaves from three plutons in the Chilliwack batholith have been compared with contemporaneous mafic stocks in order to determine (1) the processes by which mafic and felsic magmas hybridize in the plutonic environment and (2) whether analysis of early-formed enclave minerals, particularly apatite, can provide a means of seeing through hybridization effects and deciphering the original t...
