Four full paragraphs and not a damn word about what minerals the “jackpot” is. I’m getting sick of these articles where the title is nothing but hype. All designed to get you to click the link and get you to spend enough time there for a gang of popup adds to explode across the page or in the margins.

Crap.

Dang they found my mineral cache...

Because they don't know. They have just imaged the mineral veins, not analyzed them.

Judging by appearances (always dangerous), they are likely to be some type of carbonate (like calcite) or evaporite (like salt).

Obviously Kryptonite.

Blake said, "Telegraph Peak has almost no evidence of clay minerals, the hematite is nearly gone and jarosite abundance is down. The big thing about this sample is the huge amount of cristobalite, at about 10 percent or more of the crystalline material." Cristobalite is a mineral form of silica. The sample also contains a small amount of quartz, another form of silica. Among the possibilities are that some process removed other ingredients, leaving an enrichment of silica behind; or that dissolved silica was delivered by fluid transport; or that the cristobalite formed elsewhere and was deposited with the original sediment.
