Petroporphyrins showing both a free C-7 position and a C-l 3 to C-l 7 substitution pattern typical of chlorophyll c fossils were isolated from two Cretaceous Moroccan oil shales. They may arise from chlorophyll r+ or a related compound like the 7-fomtyl analog. The recent assignment of specific prec

The isolation and structural determination (n.m.r., n.O.e., synthesis) of a C33 member of the DPEP series from Boscan crude oil indicates that total reduction of
A number of samples of shale oil prepared under various conditions have been examined by 13C n.m.r. using multiple-pulse techniques that allow carbon-type assignments. Previous assignments by Netzel et a/. (Fuel 1981,60,307) are confirmed and several new ones made. Product chemistry is then examined
Oil shale of the Green River Formation (Eocene) in the Piceance Creek Basin, Colorado contains seven major iron-bearing minerals: pyrite, marcasite, pyrrhotite, Mg-siderite, Fe-dolomite, ankerite and Ca-ankerite. Only recently have workers recognized that these rocks contain large quantities of iron
