Notes on Bore No. 7. 
Down to 142 ft. 3 in. the deposits are chiefly subaerial accumulations, 
some of the upper 130 feet being derived from granitic rocks, as evidenced 
by the quartz and mica. Below 130 feet evidence of flu via tile action is 
present; whilst at 142 feet the concretionary structure in the rock would seem 
to indicate ancient surface conditions. From 142 ft. 3 in. to the limit of the 
present boring—155 feet—the deposit is clearly of Kalimnan age, as shown 
by so typical a series of fossils as Volvulella tatei, Marginella muscarioides, 
Liopyrga quadricingulata and Montacuta sericea.
