Hello everyone. My group and I recently encountered in our project black substance looked like a charcoal when its dry but its like oil when wet. Its like a several small logs of wood more than 1 meter in size. We encountered this layer after breaking through 2 layers (3ft each) of piling of cement-like stones @45ft. And we noticed there's a bit odd about the water temperature because its warm. Usually water temperature in that layer 60ft would be very cold. And if there's volcanic activity there should be sulfur nearby but there's none. We're still digging up significant amount of black substance in the sandy layer more like a mixture of fine sand and gravel. As of now, the project is stopped temporarily due to financial constraints.
