Atlantic, and Emeishan, China, large igneous provinces (LIPs). While package
thicknesses are representative, individual unit thicknesses are schematic, and
x -axis widths emphasize distinctions in rock types. MVD c volcaniclastic

the northeast to reworked volcaniclastic and epiclastic deposits to the southwest.
Primary deposits consist of c . 300 m of: fallout tuffs; surge deposits with
abundant accretionary and armored lapilli; bomb beds; and scoria deposits with
three-dimensional cone morphology (Ukstins Peate et al ., 2003 ). These transition
