Layer No4 is defined as slightly to fresh granite rock. In this one, the color of rock

didn’t changed rock of materials (ogiginal color increases) whole texture and structure

same intack rock, hard deposit. The elevation of surface layer is encounterd in borehole

from +34.10m(BH01) to +84.90m(BH02). However boreholes finished we was undefine

bottom of layer at BH02.

At borehole BH01, the depth of borehole is from 39.0 m to 41.m. The rock had

fissured and weathered. The composition main is sandy clay mixed grevel, boulder

(layer V).
