Paleoenvironmental, paleoecological and thermal metamorphism implications on the organic petrography and organic geochemistry of Tertiary Tanjung Enim coal, South Sumatra Basin, Indonesia
Organic petrography and organic geochemistry studies have been conducted on Tertiary age coals from Tanjung Enim, South Sumatra Basin, Indonesia. The coals are of subbituminous rank (vitrinite/huminite reflectance, VRr, = 0.35 - 0.46%). In this area, the coals were also locally intruded by …

Arsenic mobility in a changing northern climate: Implications for geochemical baselines and long-term stability of contaminants in lake systems
… This study integrates As geochemistry, organic petrography, paleoclimate proxies (particle size, organic matter (OM) type and quantity), and radiometric dating (14C and 210Pb) to determine the influence of past and present climate warming on the long-term stability of As in lakes …
