The identified species have close affinity to Tethyan faunas known from parts in Asia, Africa Invertebrates and Europe. They indicated shoaling of the sea floor persisted throughout the deposition of the Tuwaiq Jurassic Saudi Arabia Mountain Limestone, in water depth ranging from 20 to 30 m. The low diversity of invertebrates in Tuwaiq Mountain Limestone the studied section may attribute to paleoenvironmental conditions prevailed during the Callovian age as high rate of sedimentation. -

From a geographical perspective, it is considered a subcontinent of Asia.[3] It is the largest peninsula in the world, at 3,237,500 km2 (1,250,000 sq mi).[4][5][6][7][8] The peninsula consists of the countries Yemen, Oman, Qatar, Bahrain, Kuwait, Saudi Arabia and the United Arab Emirates.[9] The peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and southwest, the Persian Gulf to the northeast, the Levant to the north and the Indian Ocean to the southeast. The peninsula plays a critical geopolitical role in the Arab world due to its vast reserves of oil and natural gas. The most populous cities on the Arabian Peninsula are Riyadh, Dubai, Jeddah, Abu Dhabi, Doha, Kuwait City, Sanaʽa, and Mecca. Before the modern era, it was divided into four distinct regions: Red Sea Coast (Tihamah), Central Plateau (Al-Yamama), Indian Ocean Coast (Hadhramaut) and Persian Gulf Coast (Al-Bahrain). -
Identification and Characterization of Near Surface Cavities in Tuwaiq

Weak zones or cavities Karsts; near surface can be potentially dangerous and several problems are associated with collapse of Tuwaiq Mountain Lime- roads or buildings accompanied by subsidence phenomena. Karst environments are characterized stone; by distinctive landforms, which are related to dissolution and dominant subsurface drainage. The 2-D ER interaction of limestone with water is able to create karst features such as cavity, pinnacle, boulder and sinkhole through the dissolution process. The existence of subsurface karst features are always a matter of concern to engineers before any development starts because these features could cause disaster in the future. The study was conducted at Tuwaiq Mountain Limestone, Riyadh region, KSA with the objective to detect and treat karst features at limestone rocks. The karst features such as fill cavity, boulder, pinnacle, discontinuity and overhang were detected in the survey lines. The 2-D ER results showed a good correlation with all the borehole records in determining the subsur- face of limestone formation. -

Origin of Gypsiferous Intrusions in the Hawasina Window, Oman Mountains: Implications from Structural and Gravity Investigations
GeoArabia, 2014, v. 19, no. 2, p. 17-48 Gulf PetroLink, Bahrain Origin of gypsiferous intrusions in the Hawasina Window, Oman Mountains: Implications from structural and gravity investigations Mohammed Y. Ali, David J.W. Cooper, Michael P. Searle and Ali Al-Lazki ABSTRACT Gypsiferous intrusions are exposed in road-cuts in the south-central Hawasina Window in the central Oman Mountains. They are located at lower structural levels in the allochthonous Hawasina Complex and lie along faults that cut Upper Cretaceous structures related to the obduction of the Semail Ophiolite and Hawasina Complex deep-water sediments onto the Arabian Plate. The intrusions form gypsiferous pods that are up to 200 m long, in which the gypsum occurs as a dark, fine-grained matrix that contains a pervasive network of anastomosing veins of gypsum and anhydrite. The intrusions contain abundant sub-angular to sub-rounded litharenites, and less common fragments of chert and fine- grained limestone. Although these clast types are undated, their petrographic characteristics suggest they originate from the local Hawasina (Hamrat Duru Group) country rock. Very well-rounded pebbles and cobbles of feldspathic litharenites, some of which show a well-developed cleavage, and rarer cobbles of well-rounded vein quartz appear to have come from the basement. Gravity investigations indicate salt diapirs are not present beneath the Hawasina Window. Instead, the gypsiferous intrusions are interpreted as having been brought up from depth during compression to form disconnected pods along deep-rooted faults, bringing with them small amounts of the basement country rock. Strontium isotope analysis and regional considerations, in particular the distribution, age and nature of other evaporite units on the eastern Arabian Plate, suggest the gypsum may have its origins in the Neoproterozoic (Ediacaran) to lower Cambrian Ara Group evaporites, perhaps from a previously unknown extension of the Fahud Salt Basin beneath the Hawasina thrust sheets. -

The Impact of the COVID-19 Pandemic on the Energy Sector in the Kingdom of Saudi Arabia: The Future of Renewable Energy after the Crisis Sarah Alotaibi Special Report February, 2021 / Jumada I 1442 H. 1 The Impact of the COVID-19 Pandemic on the Energy Sector in the Kingdom of Saudi Arabia: The Future of Renewable Energy after the Crisis Special Report Table of Contents Abstract 6 Introduction 7 Section 1: Implications of the COVID-19 pandemic and change in domestic energy demand 9 Oil 9 Energy diversification strategy 10 Gas 10 Renewable energy sources 11 Growth of renewable energy projects investments 12 Section 2: The impact of COVID-19 on electricity consumption 16 Enhance energy efficiency policies 19 Electricity sector reforms 19 Section 3: Transition towards a sustainable energy system 22 Conclusion 23 5 Abstract This report focuses on the impact of the COVID-19 lockdown on domestic electricity consumption in the Kingdom of Saudi Arabia. It includes a breakdown by percentage of how different energy sources, including gas and renewable energy (RE), are contributing to the total energy mix during the crisis. Finally, it highlights the importance of renewable energy sources for the sector after the pandemic. 6 Introduction The number of infections from the coronavirus has exceeded 56 million, resulting in more than 1 million deaths. Governments across the globe are continuing to take measures to combat the spread of the epidemic and reduce its economic and social repercussions.(1) In many countries, this one crisis has led to a series of consecutive crises that revealed profound weaknesses in their economies, necessitating a review of sustainability policies according to these new perspectives to overcome it. -

Othman Llewellyn's Arabia: a Guide to Mountains of Unusual Beauty
OTHMAN LLEWELLYN'S ARABIA: A GUIDE TO MOUNTAINS OF UNUSUAL BEAUTY (Notes taken by John Ady based on the talk given by Mr. Llewellyn on January 17, 1991) Those who attended the meeting held in January 1991, on the evening of the outbreak of the Kuwait war, when the speaker kept nobly to his promise to get to us from Riyadh, will remember his lyrical descriptions of the beauty of Arabian mountain landscapes. He had seen these during several years of extensive travel around Saudi Arabia on behalf of the National Commission for WilcJIife Conservation and Development (NCWCD), helping to select areas to be designated for protection for the value of their vegetation, wildlife and scenery. As a reminder for those who may be able to visit them, we include a map marked with the localities he described (Figure 1). We have added a few further places, all of them mountain areas of unusual beauty, with brief notes on their character based on his descriptions. This is neither a guide nor a guarantee of their accessibility. In most cases a four-wheel drive vehicle is essential to reach them. 1: Jabal Aja' & Jabal Salma These are two separate but nearby mountain ranges, each a maze of pinnacles and domes of red, rose and lavender granite with many perennial and ephemeral springs. They are full of acacia and palm groves nestling in the heights of the mountains with one of the most wonderful displays of spring flowers in Arabia when the rains have been good. It holds a few small herds of ibex, also wolves and ratels, is said to have caracal and may have some of the largest colonies of griffon vultures in the world.
