... assemblage (<2680–2670 Ma in the southern Abitibi). The orebodies define two main mineralized trends, which are oriented subparallel to the NW-striking S 2 cleavage and the E-striking, S-dipping Sladen fault zone. This syn- to post-D 2 ductile-brittle to brittle Sladen fault zone is mineralized for more...

... is characterized by a Au-Te-W-S-Bi-Ag ± Pb ± Mo metallic signature, mainly consists of quartz-carbonate vein stockworks and replacement zones with disseminated pyrite. The ore zones are dominantly oriented subparallel to a NW-striking S 2 foliation and to the E-striking and S-dipping Sladen fault, thus forming NW...

..., and clastic margin studies. Many of Southeast Asia's largest oil and gas fields (e.g., Minas ∼4 × 10 9 bbl of oil) are found within the Paleogene nonmarine rifts of Indonesia, where production has been declining since 1993 ( Sladen, 1997a ; Doust and Sumner, 2007 ).
