Geology Report EssayIn article 64, brink Placers Containing Radioactive Minerals, Bay of Bengal, East Pakistan the geologists have thoroughly researched the rocks and minerals of beach placers that ex cardinald 100 miles southeastward along the Bay of Bengal near East Pakistan. During the 1961 study the geologists discovered that the placers sway heavy hot minerals including monazite, ilmenite, and zircon. In the smooth along the beaches, the geologists, found 10 to 30 percent of heavy minerals that exceed 2. 8 specific gravity.Of the ten randomly dispersed placers analyze along the oast, geologist found they all contained teentsy concentrations of these heavy radioactive minerals. The minerals studied in the placers were in layers between 1 and 2. 5 feet thick and located near the beach erupt along with others buried in sand dunes. They believe the placers were form with or by a conspiracy of waves, wind, and the natural down flow of creeks/rivers. Due to the difference of each separately located placer, geologists noticed shred sizes and the sorting of the minerals differ from placer to placer.They discovered the lenses with the majority of eavy minerals is finer grained, better screen out, and better rounded and contains magnetite. In the sinoatrial node at the northernmost tip, they found it differs from the others. It had black sand as opposed to white and it laid on top of a mud platform. Also, according to the survey, geologists found this placer to be less radioactive than the rest of placers researched. on the whole of the placers are oblong in shape and are very large. Each placer is tens of hundreds of feet wide and can load out to be several miles long. The geologists surveyed the placers using an airborne radiometric survey.After ll of the research the geologists and scientists found that all of the placers contain radioactive minerals as well as non-radioactive minerals. Reasoning and Application I specifically chose this article because I find radioactive minerals, and anything geological related to the ocean, interesting. I grew up surfing in a small beach town near Santa Barbara so any type of geology related to the oceans and beaches interest me. Also, one of the to a greater extent interesting topics learned in my geology class were the different types of minerals and how their individual physical structure can be altered due to earths natural forces.After studying geology this semester I was able to fully understand how these placers were formed along with why these heavy minerals formed in layers and were denser than the sand and other rocks. It helped me understand why and how geologists surveyed these radioactive minerals. Also, I completely understood how these minerals were sorted and the different physical structure of these well and poorly sorted minerals. I can honestly say that before taking this class I would have no idea what this article was about. Now I was fully able to grasp all of the i nformation provided in the article.
