“…Since aqua regia is an oxidizing agent, it is likely to dissolve organic-bound sulfur and sulfide minerals, and those were probably the main sulfur phases in our samples. Aqua regia does not fully dissolve barite (Abbasi et al, 2016); however, barite was not visible in our samples and not detected by XRD (Table S2, Section 4.1.2), and so this issue would likely not be relevant for this study. Additional method development would be required for rock samples containing significant barite.…”

On the anoxic Archean Earth, prior to the onset of oxidative weathering, electron acceptors were relatively scarce, perhaps limiting microbial productivity. An important metabolite may have been sulfate produced during the photolysis of volcanogenic SO2 gas. Multiple sulfur isotope data can be used to track this sulfur source, and indeed this record indicates SO2 photolysis dating back to at least 3.7 Ga, that is, as far back as proposed evidence of life on Earth. However, measurements of multiple sulfur isotopes in some key strata from that time can be challenging due to low sulfur concentrations. Some studies have overcome this challenge with NanoSIMS or optimized gas‐source mass spectrometry techniques, but those instruments are not readily accessible. Here, we applied an aqua regia leaching protocol to extract small amounts of sulfur from whole rocks for analyses of multiple sulfur isotopes by multi‐collector inductively coupled plasma mass spectrometry (MC‐ICP‐MS). Measurements of standards and replicates demonstrate good precision and accuracy. We applied this technique to meta‐sedimentary rocks with putative biosignatures from the Eoarchean Isua Supracrustal Belt (ISB, >3.7 Ga) and found positive ∆33S (1.40–1.80‰) in four meta‐turbidites and negative ∆33S (−0.80‰ and −0.66‰) in two meta‐carbonates. Two meta‐basalts do not display significant mass‐independent fractionation (MIF, −0.01‰ and 0.16‰). In situ Re–Os dating on a molybdenite vein hosted in the meta‐turbidites identifies an early ca. 3.7 Ga hydrothermal phase, and in situ Rb–Sr dating of micas in the meta‐carbonates suggests metamorphism affected the rocks at ca. 2.2 and 1.7 Ga. We discuss alteration mechanisms and conclude that there is most likely a primary MIF‐bearing phase in these meta‐sediments. Our new method is therefore a useful addition to the geochemical toolbox, and it confirms that organisms at that time, if present, may indeed have been fed by volcanic nutrients.

“…Vegetation, soil, water resources, and human can be threatened by wastes that were left over including lead, zinc, cadmium, and some toxic minerals. 117,118 These wastes with a widespread distribution have the high potential of pollution.

Hyperspectral imaging has been used in a variety of geological applications since its advent in the 1970s. In the last few decades, different techniques have been developed by geologists to analyze hyperspectral data in order to quantitatively extract geological information from the high-spectral-resolution remote sensing images. We attempt to review and update various steps of the techniques used in geological information extraction, such as lithological and mineralogical mapping, ore exploration, and environmental geology. The steps include atmospheric correction, dimensionality processing, endmember extraction, and image classification. It is identified that per-pixel and subpixel image classifiers can generate accurate alteration mineral maps. Producing geological maps of different surface materials including minerals and rocks is one of the most important geological applications. The hyperspectral images classification methods demonstrate the potential for being used as a main tool in the mining industry and environmental geology. To exemplify the potential, we also include a few case studies of different geological applications.

“…For geological samples such as soils and rocks, there is an additional challenge for Ra determination by ICPMS, which is to achieve complete recovery of the element from the sample matrix. Sulfates of Sr, Ba, and rare earth elements (REE) are very difficult to dissolve, and Ra can be present as inclusions in such minerals. ,, For Ra determination, digestion with HNO 3 , HF, HCl, or combinations of these are commonly used; however, this may not necessarily result in a complete recovery of Ra from the sample , and consequently lead to underestimation of the Ra content.…”

High Throughput, Direct Determination of ²²⁶Ra in Water and Digested Geological Samples

A method was developed for direct measurements of 226 Ra in water samples with triple quadrupole inductively coupled plasma mass spectrometry (ICP-QQQ). The limit of detection was 0.42 pg L −1 226 Ra (15 mBq L −1 , 0.42 pCi L −1 ), which is compliant with the specifications for methods used for routine analysis of drinking water quality according to European and U.S. regulations. The use of N 2 O as reaction gas ensured that no separation before analysis was necessary. Water samples with high total dissolved solids (conductivity >100 mS cm −1 ) were also successfully analyzed after a simple dilution, yet the associated detection limit was higher (17 pg L −1 , 0.61 Bq L −1 , 16 pCi L −1 ). 226 Ra content in soil and rock samples was determined with the same method after acid (HNO 3 + H 3 PO 4 ) digestion and dilution, resulting in a limit of detection of 0.75 ng kg −1 (27 Bq kg −1 , 0.74 nCi L −1 ). Analysis of water samples was achieved within 2 min on a running instrument, while the preparation and analysis of 15 geological samples can be completed in 3 h. The key advantages of this direct analysis method are short preparation time, low labor intensity, low sample input (2 mL for water samples, 0.2 g for geological material), high sample throughput (2 min sample to sample, >150 samples measured in 8 h), and use of standard ICP-QQQ hardware. Overall, the proposed method offers a new opportunity for measuring a large number of samples with minimal effort and, in turn, for improving emergency preparedness, environmental monitoring, and data collection for environmental modeling.
