The rest of the ore zone, the lower 12.5 feet, has become part of A Lower. If a drillhole does not reach as low as 4130 elevation, then all the ore remains in the A Upper bed and is unaffected. Conversely, if the ore never exceeds elevation 4130 in a particular drillhole, then it is assigned bed A Lower for all the ore sample points.

Prospecting - Official SevTech: Ages Wiki

One of the first major roadblocks that many people run into in Age 1 progression is finding ore. In SevTech: Ages, ore is controlled by a mod called Geolysys, and is not randomly distributed throughout the world like in vanilla Minecraft. Instead, the ore is aggregated into large veins of ore, where hundreds of ore may be located. There are a couple of steps to finding the ore: 1. …

Pyrite formation from FeS and H2S is mediated through ...

Pyrite is the most abundant iron−sulfur mineral in sediments. Over geological times, its burial controlled oxygen levels in the atmosphere and sulfate concentrations in seawater. However, the mechanism of pyrite formation in sediments is still being debated. We show that lithotrophic microorganisms can mediate the transformation of FeS and H2S to …

Sulfur analysis in an ICP instrument - Inorganic Ventures

Many sulfur compounds have a large enough vapor pressure to give a higher nebulization efficiency and thereby a false high signal. Also beware that sulfide will slowly air oxidize to elemental sulfur in basic media which is not a problem so long as the elemental sulfur does not drop out of solution. Analyze the samples ASAP.
