Abstract: | Nodular limestones of Hanguletag formation in the Kuruktag are part of a type of warty sedimentary sequence.The nodular limestone is developed in the slop of platform margin and was rebuilt by slumping and gravity flow.There are three types of nodular limestone including mud-rich,transitional and lime-rich.The mud-rich nodular limestone was deposited under the CCD and was dissolved in the deep sea-water.The transitional nodular limestone was deposited near the CCD and was dissolved by both bottom current of sea floor and deep sea water.The lime-rich nodular limestone was deposited above CCD and was rebuilt by periodical gravity flow and dissolved by bottom current of sea floor.These lithologic associations suggest that the Kuruktag was formed during a stage of rapid transgression in the early-Ordovician |
