Tar pit at Tierra La Brea, Trinidad An anticlinal trap is feeding the tar pit on the surface through the vertical fracture in the strata (indicated by the red arrow). Once the crude oil reaches the surface, evaporation takes place and lighter hydrocarbons are vaporized, leaving behind sticky asphalt.

Tarpit (networking) A tarpit is a service on a computer system (usually a server) that purposely delays incoming connections. The technique was developed as a defense against a computer worm, and the idea is that network abuses such as spamming or broad scanning are less effective, and therefore less attractive, if they take too long.
McKittrick Tar Pits – series of natural asphalt lakes situated in McKittrick near Bakersfield, California, US. The tar pits have trapped and preserved many Pleistocene Age animals. Pitch Lake – largest natural deposit of asphalt in the world, located at La Brea, Trinidad and Tobago. From this source many of the first asphalt roads of New ...
The Tar Sand Triangle deposit, for example, is roughly 6% bitumen. [24] Bitumen may occur in hydrothermal veins. An example of this is within the Uinta Basin of Utah, in the US, where there is a swarm of laterally and vertically extensive veins composed of a solid hydrocarbon termed Gilsonite.
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust. Reservoirs are broadly classified as conventional ...
The pits are the most extensive asphalt lakes in the state. [1] The McKittrick Tar Pits are one of the five natural asphalt lake areas in the world, the others being Tierra de Brea in Trinidad and Tobago, Lake Guanoco in Venezuela and the La Brea Tar Pits (Los Angeles) and Carpinteria Tar Pits (Carpinteria) both also located in the US state of ...
