This activity was northwest of Mono Basin and included the formation of Aurora Crater, Beauty Peak, Cedar Hill (later an island in the highest stands of Mono Lake), and Mount Hicks.Mono Lake is believed to have formed at least 760,000 years ago, dating back to the Long Valley eruption.It is also believed that calcite crystallization inhibitors such as phosphate, magnesium, and organic carbon may aid in the stabilization of ikaite.This has led scientists to believe that thinolitic tufa is an indicator of past climates in Mono Lake because they reflect very cold temperatures.These pioneering works in tufa morphology are still referred to by researchers today and were confirmed by James R. The tufa types can roughly be divided into three main categories based on morphology: These tufa types vary interchangeably both between individual tufa towers but also within individual tufa towers.There can be multiple transitions between tufa morphologies within a single tufa tower.
As stated above, calcite/aragonite-DIC fractionation can only explain an enrichment of 1-3‰ compared to lake water, i.e. The reason for this small δC enrichment of tufa is still unclear and requires follow-up studies.
These subsurface waters may have a very different composition compared to both Mono Lake waters and riverine surface waters. formation of calcite from aragonite) or meteoric diagenetic effects could have some control on the isotopic composition as well.
