interval_notes:	Schematically, the thickest carbonate debris flow at Guandao is shown here -- for graphic purposes, it is shown as spanning 0.5 myr (0.25 on either side of the MT4r/MT4n polarity boundary; although it would be an instantaneous event.

base notes	In the Anisian, the Guandao succession has facies of "deep-marine slope sedimentation consisting of pelagic lime-mudstone punctuated by carbonate packstone–grainstone turbidite and debris flow breccia beds." (Lehrmann et al., 2015). Change in facies at Wantao is essentially base of the MT3n polarity zone (used here).				comp notes
