... that dolomite was added to the Riversleigh Siltstone during mineralization. Massive, botryoidal, and fine-grained disseminated, bedding-parallel pyrite (FP 1 ) occurs as 2- to 50-cm-thick beds within the mineralized zone (Figs. 4e , 5 , 6a ) and may be contemporaneous with FD 1 dolomite. Illite-filled...
