PREMISE OF THE STUDY: Gypsum endemism in plants (gypsophily) is common on gypsum outcrops worldwide, but little is known about the functional ecology of Chihuahuan Desert gypsophiles. We investigated whether leaf chemistry of gypsophile lineages from the northern Chihuahuan Desert are similar to leaves of related nonendemic (gypsovag) species relative to their soil chemistry. We expected ...

Recent and ancient evolutionary events shaped plant elemental ...

Introduction. Plant life, in all its diversity, is the result of the combination of up to 30 chemical elements (Ågren, 2008).The ultimate way in which such elements combine and give rise to the elemental composition of plants depends on processes of nutrient uptake, use, storage and translocation (Baxter, 2009).Although some of these processes are conserved across the phylogeny, many are ...

Stratum mining protocol - Bitcoin Wiki

The mining extensions were announced after the community had spent months developing a mostly superior open standard protocol for mining (getblocktemplate). Because stratum's mining extensions launched backed by a major mining pool, GBT adoption suffered, and decentralised mining is often neglected while stratum is deployed. References

Opencast Mining (Quarrying): Methods, Advantages & Disadvantages ...

Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes. The mineral exposed is completely extracted.

Gypsum Mining | Processing Equipment | Flow Chart | Cases - JXSC

Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers. It forms in lagoons where ocean waters high in calcium and sulfate ...

Abundant resources and efforts have been employed in the search for life on Mars. Satellites, landers, and rovers have tested atmospheric gases, general sediment and rock compositions, and images of Mars surface in an effort to detect biosignatures left by any possible modern or ancient life. Chloride and sulfate minerals suggestive of past acid saline lakes have been found on Mars.

Notes on Chemical Methods of mineral Extraction - Blogger

The method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores (as high as 1,000 kg of acid per tonne of ore, but 500 kg is more common.)

We expected widely distributed gypsophiles (hypothesized to be older lineages on gypsum) would have distinct leaf chemistry from narrowly distributed, relatively younger lineages endemic to gypsum and gypsovags, reflecting adaptation to gypsum. METHODS: We collected leaves from 23 gypsophiles and related nonendemic taxa growing on nongypsum soils.
