Editing Tar pit (section)

=== [[La Brea Tar Pits|La Brea]] ===
The La Brea Tar Pits are located in [[Los Angeles]]. The petroleum that is seen on the surface is sourced from the [[Salt Lake Oil Field]] reservoir and the oil sands in the [[Repetto Formation|Repetto]] and [[Pico Formation|Pico formations]].<ref name=":5">{{Cite journal|last1=Weber|first1=Derek|last2=Marquez|first2=Bertha A.|last3=Taylor|first3=Charnise|last4=Raya|first4=Paul|last5=Contreras|first5=Paul|last6=Howard|first6=David|last7=Nwachuku|first7=Ikenna|last8=Fusco|first8=Katie|last9=Morales|first9=Fernanda|last10=Doezema|first10=Lambert A.|date=2017-09-01|title=Macroseepage of methane and light alkanes at the La Brea tar pits in Los Angeles|url=https://doi.org/10.1007/s10874-016-9346-4|journal=Journal of Atmospheric Chemistry|language=en|volume=74|issue=3|pages=339–356|doi=10.1007/s10874-016-9346-4|bibcode=2017JAtC...74..339W|s2cid=101426941|issn=1573-0662|url-access=subscription}}</ref> These oil deposits were formed during the Miocene Epoch when marine plankton organisms accumulated in an ocean basin.<ref name=":13">{{Cite web|title=La Brea Tar Pits and Hancock Park {{!}} La Brea Tar Pits|url=https://tarpits.org/experience-tar-pits/la-brea-tar-pits-and-hancock-park|access-date=2021-04-26|website=tarpits.org|language=en}}</ref> Over time, sediments buried the organisms 300 to 1000 meters below Earth's surface, subjecting them to high pressures. This process turned the organic matter into oil. The 6th Street Fault that cuts through the Salt Lake Oil Field is the conduit that feeds the La Brea Tar Pits.<ref name=":5" /> Petroleum migrated to the surface over time, trapping and preserving animals and plants for the past 50,000 years.<ref name=":13"/>
