Hokusatsu erupted expansive plateau lavas ranging from 100-200 m in thickness (Hosono et al., 2003). Lava compositions mostly range from basaltic to andesitic. While silicic deposits were produced throughout Hokusatsu's eruptive history, they mostly dominate the youngest products. Hokusatsu lavas are Plio-Pleistocene in age, ranging from 0.35 to 3.4 Ma (Nakano et al., 2001; Hosono et al., 2008). They are calc-alkaline in composition (Hosono et al., 2008). The Hokusatsu volcanic region is also noted for its silver and gold deposits and is therefore of economic importance to Japan (Hosono et al., 2008).
