In these cases, pockmarks have been interpreted as the morphological expression of gas or oil leakage from active hydrocarbon system or a deep overpressured petroleum reservoir.
As a consequence, these areas are concentrated with toxic compounds due to mineral and hydrocarbon exploration; this exploitation has increased in the last two decades.
The example given, paraffin wax, is a member of a family of hydrocarbon molecules of differing chain lengths, with high-density polyethylene at the long-chain end of the series.
