interval_notes:	Medium-dark-grey, nodular lime mudstones containing ammonoids, conodonts and thin-shelled bivalves, the Zhuganpo Formation. The upper part of this thin pelagic limestone contains many muddy intraclasts, some slightly bored and encrusted, indicating incipient cementation. Base is one 100-kyr cycle into Normal-polarity below a reversed; interpreted here as upper UT1n.2n.
