Pitch Lake
The Pitch Lake is the largest natural deposit of
Pitch Lake is a popular tourist attraction, including a small museum, from where official tour guides can escort people across the lake. The lake is mined for asphalt by Lake Asphalt of Trinidad and Tobago.
History
The Pitch Lake has fascinated explorers and scientists, attracting tourists since its re-discovery by Sir
In the 1840s, Abraham Pineo Gesner first obtained kerosene from a sample of Pitch Lake bitumen.[5]
In 1887,
Since its re-discovery, there have been numerous research investigations into the use and chemical composition of this material. There have been countless theories, postulations, and conclusions as to the size, source, and origin of the asphalt.[citation needed]
Geology
The origin of The Pitch Lake is related to deep
The regional geology of southern Trinidad consists of a trend of
The first wells were drilled into Pitch Lake
Microbiology
Evidence of an active microbiological ecosystem in Pitch Lake has been reported. The microbial diversity was found to be unique when compared to microbial communities analyzed at other hydrocarbon-rich environments, including La Brea tar pits in California, and an oil well and a mud volcano in Trinidad and Tobago.[11] Archaeal and bacterial communities co-exist, with novel species having been discovered from Pitch Lake samples.[8] Researchers have also observed novel fungal life forms which can grow on the available asphaltenes as a sole carbon and energy source.[12]
