Synsedimentary dolospar cementation: a possible Devonian example in the Camsell Formation, Northwest Territories, Canada1
ABSTRACT A unique association of beds containing fenestral pore‐filling medium crystalline dolomite with beds of dolospar and quartz sandstone occurs in the Lower Devonian Camsell Formation. Many of these sandstones consist almost entirely of dolospar sand. Sedimentological, petrographic, cathodolum...
