“…Five samples of potassium feldspar (table 6) had a range from 70 to 300 ppm. Slawson and Nackowski (1959) reported an average of 55+18 ppm for lead in potassium feldspars from the Little Cottonwood stock. Another possible source of lead in stream sediments is from weathering of joint planes; nine samples taken from these joint planes ranged from 10 to 1,000 ppm lead (table 7).…”

Bureau of Mines during 1973 and 1974 covered 53 square miles (137 kin 2) in the rugged central Wasatch Range near Salt Lake City, Utah. The study by the U.S. Geological Survey consisted of geological, geochemical, and geophysical investigations; the study by the U.S. Bureau of Mines covered a search of public records for mining-claim locations and the mapping, sampling, and examining of prospect workings and mineralized areas. The area lies at the west end of an east-northeast alinement of mid-Tertiary intrusive rocks that define a mineral belt containing silver-lead-zinc deposits. The highly productive Park City district and the Cottonwood-American Forks districts are within the belt to the northeast of the study area. Mineral commodities in the area include molybdenum, silver, lead, tungsten, zinc, and copper. Part of the area may have a future potential for minable deposits containing molybdenum but little economic potential for other metals. The area has little or no potential for coal, oil, gas, and geothermal resources. The Lone Peak area is underlain chiefly by Precambrian and Paleozoic sedimentary rocks and by a mid-Tertiary stock of quartz monzonite. The northern part is underlain predominantly by the quartz monzonite of the Little Cottonwood stock and by smaller peripheral areas of Precambrian sedimentary rocks and a thin sequence of Paleozoic beds. South of the stock, and separated from it by the Deer Creek fault, the area is underlain by younger Precambrian sedimentary rocks and a much thicker section of Paleozoic rocks. These sedimentary rocks are arched into a dome and broken by a complex of generally east-west faults. The sections of Paleozoic rocks of diverse thicknesses exposed north and south of the Deer Creek fault have been brought together in the central Wasatch Range by the Charleston-Nebo thrust of Late Cretaceous age, now concealed in the hanging wall of the Deer Creek fault. The investigations resulted in the collection of 561 samples: 291 stream sediment and 270 rock samples. Many of the rock samples were collected from mines and prospects. The aeromagnetic data reflect and define the limits of intrusive igneous bodies, some of which contain submarginal-grade molybdenum deposits and minor occurrences of tungsten.

“…However, the potential for lead to be present in a minute or large amount in potash ingested in Anambra State, Nigeria, remains unclear. But there is a linkage between the existence of trace levels of Pb in potash feldspars and the emergence of Pb ore deposits that are associated with igneous rocks [9].…”

Geologically known as trona, evaporite, or locally known as greyish potash, akanwu, or kaun, it serves a multitude of purposes in Nigeria. These include, but are not limited to, softening legumes and flesh, augmenting the therapeutic attributes of herbal expectorant remedies, and reducing male libido or fertility. The unrestricted consumption and accessibility of this salt in the local markets of Anambra State, Nigeria, are due to its affordability and accessibility. Currently, there is no investigation into the comprehensive impact of potash's antioxidant properties at various low doses on male fertility. This led to a study that lasted for 28 days and involved rats weighing between 120 g and 140 g. The rats were separated into four groups, with each group consisting of seven rats. Group A was the control group, while groups B, C, and D were the test groups administered doses of 150 mg/kg, 300 mg/kg, and 450 mg/kg of potash, respectively. At the end of the study, the antioxidant properties of potash were tested. Prostate, gland, testis, and blood were collected and analyzed. Data was analyzed with the statistical social science (SPSS) version 27. Results were presented as mean ± standard deviation (SD). A one-way analysis of variance (ANOVA) was used to compare the mean values. Our study found a significant (p<0.05) dose dependent decrease in fertility hormones and semen parameters. Prostate specific antigen (PSA) increased dose-dependently compared to the control. Our findings indicate that trona is rich in antioxidants.
