摘要：

Trends in element compositional variation among samples at the Viking lander sites on Mars provided evidence for multiple geochemical components in the soils. A simple two-component model can explain all pair-wise trends of eight elements analyzed. Component A contains Si and most or all the Al, Ca, Ti, and Fe. Component B, which is 16 +/- 3% by weight of the total, contains S and most or all the Cl and Mg. These results constrain several models of Martian soil mineralogy but are consistent with a mixture of silicates and salts.
