Geological Mapping and samples collection in red sea state, sudan

captured in the process of Geological Field Mapping in the south of Malawi. Geological field mapping is the process of creating a detailed and accurate representation of the geological features and structures of an area through direct observation and measurement in the field. It involves recording and mapping the distribution of different rock units, their relationships, and their structural and sedimentological characteristics.

As we navigate maps today, it's worth remembering the proverb "When you eat the fruit, think of the man who planted the tree." In this case, let's acknowledge Glen F. Brown and the countless individuals who contributed to this invaluable resource that continues to benefit us all. A special thanks to Rami Kamal for sharing this article, highlighting a piece of history that many would otherwise have to delve years into libraries to uncover.

Old Photos Of Arabia Saudi Arabia 🇸🇦 The First Geological Maps of the Arabian Peninsula Glen Francis Brown (1911-2001) (see Photo) In 1944, his Majesty King Abdulaziz Al Saud approached the U.S. 🇺🇸 for an expert who could assist with the identification and plotting of the kingdom's natural resources, particularly its groundwater reserves. The individual who arrived, Glen Francis Brown, pioneered a partnership between the United States Geological Survey (USGS) 🇺🇸 and the government of Saudi Arabia 🇸🇦 that was to span the next 5 decades. Glen F. Brown oversaw the creation of a highly detailed map of the Arabian Peninsula, the first modern map at the scale of 1:2,000,000. The map was based on a series prepared by the U.S. Geological Survey and the Arabian American Oil Company under the joint sponsorship of Saudi Arabia 🇸🇦 and the U.S. State Department 🇺🇸. The map also included present-day Kuwait, Qatar, Bahrain, United Arab Emirates, Oman, and Yemen. The plan for a cooperative mapping project was first conceived in 1953. By 1955, an agreement was established between Saudi Arabia 🇸🇦, the U.S. Department of State 🇺🇸, and the Arabian-American Oil Co. , to make available the areal geology mapped by both Aramco and the U.S.G.S. The plan provided for 21 maps on a 1:500,000 scale in both geologic and geographic versions; and a peninsular geologic map on a scale of 1:2,000,000. The first geographic quadrangle was published in 1956 and the last in 1962. A preliminary edition of a 1:2,000,000 scale peninsular geographic map was compiled and published in both English and Arabic, in 1958. A final version appeared in 1963 incorporating additional photographic, topographic and cultural data. This was followed by a 1967 edition that included a key with symbols for water pipelines, desert watering points, oil fields, pumping stations, refineries, and a glossary of Arabic names. To this day, all modern maps of the kingdom trace their roots back to these first publications. #OldPhotosOfArabia #USA #SaudiArabia #Aramco #USGS #FirstGeologicalMapOfTheArabianPeninsula #GlenFrancisBrown

Geological field mapping in Kenya

Geological field Study Around Blue Nile Basin (Ethiopia)

Dear GSO Member, The Geological Society of Oman (GSO) is organizing a field trip titled "Wadi Daiqa Geology", on Saturday 10th of February 2024. Field trip objective: The study of the 3,400 m thick Amdeh Formation began in an attempt to understand its age and relationships to subsurface formations in Interior Oman. The discovery of the Al Khlata P9 interval in the Wadi Daiqa inlier and the Basal Saiq Clastic interval in a wider area of the Eastern Al Hajar are bi-products of this research.

The subject of the project study is geological maps of part of the city of Riyadh.

Rock mechanics is a fascinating area of study that's especially relevant in Zimbabwe, where the geology is diverse and complex. #rockmechanics #Zimbabwegeology In Zimbabwe, rock mechanics is important for understanding and managing the country's natural resources, such as minerals and water. It's also critical for predicting and preparing for geological hazards, such as earthquakes and landslides. We're looking forward to hosting a seminar with Zimbabwe geology mentors and sharing knowledge about this important field. #Zimbabwegeologymentors #

Added silver to the Africa geological machine learning map. Here is an example I found this morning using geological machine learning to focus the eye quicky on areas of great interest in a desert or nondesert environment. It appears to be a gold-copper-silver potential deposit in Sudan, where we can see covellite and chrysocolla showing up along the dry wadi. I have marked this spot for future reference. Look at this from left to right, the starburst classification block is the source (gravity based geological machine learning), the metals surface just to the right (surface geological machine learning based on shape of the land), and the wadi furthest to the right, which we zoom into in the bottom images, shows very strongly colored covellite and chrysocolla potential mineralizations where covering clays have been cleaned off by sporatic wadi floods. Love to sample that sequence across the three classifications!
