Detrital sedimentary rock consists of the cemented-together fragments of minerals and other rocks, primarily clay, quartz, feldspar, and mica. The most abundant detrital sedimentary rock is shale, a crumbly rock made of extremely fine, microscopic-sized particles.xposed rock is the collector's fruitful ground. Many interesting minerals and fossils can be found on weathered slopes, riverbanks, and cliff faces. Human-made excavations such as road cuts and construction or quarry sites can be excellent sites for mineral hunting.

Myth. Monosodium glutamate (MSG) is the sodium salt of glutamate, the most common naturally occurring amino acid. It is used as a food additive, and confers the protein-like flavor (amino acids are the building blocks of proteins) called umami to foods when used in the proper proportions.any people report symptoms of what came to be known as âChinese Restaurant Syndrome,â which can include headache, flushing, numbness, and weakness.
