abstract |
Mafic magmatism is a prevalent geologic process on Earth, and is a principal source
of subsurface geologic change and energy influx on postNoachian Mars. While rare on
Earth, the intrusion of mafic magmas into sulfur-rich soils and rocks is expected
on Mars due to the observation of widespread high sulfur concentrations in Martian
soils. On Mars, soils have been found to be rich in sulfur. Respectively, soil samples
from Gusev Crater and Gale Crater contain between 4-8 weight percent, and 4-7 weight
percent SO<sub>3</sub>, though ammounts[sic] as high as 31 weight percent have been
measured in Gusev crater. With widespread sulfur-rich sediments and evidence of magmatism
both ancient and young, mafic intrusions into rocks and sediments bearing significant
quantities of sulfur species is expected on Mars. Processes associated with the magmatic
intrusion of a sulfur-rich host, including degassing and alteration, may provide the
requisite energy and nutrients for biological activity.<br></br><br></br>On Earth,
well exposed mafic dikes intrude the sulfur-rich sedimentary formations of the Jurassic
San Rafael Group. Approximately 200 dikes, sills, and breccias can be found in proximity
to the San Rafael Swell in Utah, and represent an Earth analog for a scenario of mafic
magma intruding sulfur-rich sediments. Here we will investigate such an analog; a
mafic dike intruding the sulfur-rich Jurassic Carmel Formation of the San Rafael
Group. |
