“…Al-Huwaidy is located about 70 km southwest of the town of Ha'il in the area of Precambrian igneous and metamorphic rocks as well as Proterozoic Arabian shield and Phanerozoic sedimentary outcrops (Ali & Alshammari 2021;Hereher et al 2012;Miller et al 1989;Powers et al 1966). Viewed from Google Earth, the landscape of the area explored is a large oasis surrounded by Alsamra mountain extension of composed volcanic rocks and connected by several small ancient water streams drained from the hilltop (jebel) into the oasis.…”

“…In the case of Ha'il region, although several prehistoric research studies have been conducted in the southern margin of the Nefud desert (Almushawh 2018;Breeze et al 2015;Jennings et al 2013;Miller et al 1989) and a number of Palaeolithic sites have been documented, there are still many unexplored areas. Some Palaeolithic sites have been recorded in the Jubbah basin, Al Maraat basin and Faid area (Groucutt et al 2021;Jennings et al 2016;Nassr & Elhassan 2020).…”

Ha’il region in northwest Saudi Arabia is characterized by the presence of oases, flat plains, Paleo-lakes, and lava fields, which are some of the main landscape characteristics in which Palaeolithic sites have been found in the region. It is located on one of the routes of early hominin dispersal across Arabia. The ongoing archaeological research made by the Paleodeserts and Disperse projects have recorded several Acheulean and Middle Palaeolithic sites in such localities as Jubbah basin in the Nefud desert (Groucutt et al. 2021; Petraglia et al. 2015; 2019), yet large parts of the region are still unexplored. The ground archaeological survey conducted by the authors at Al-Huwaidy village, 70 km southwest of Ha’il town, has led to the discovery of a unique Palaeolithic site on the margin of a palaeo-oasis, close to a volcanic mountain. The archaeological site consists of an agglomeration spread of lithics covering an area of basaltic field and outcrops. Numerous handaxes have been documented on the surface and the profiles of current water canal shafts. The site setting and the quantity and quality of lithics from Large Cutting Tools (LCT), including typical handaxes, foliate handaxes, Acheulean cores and flakes, indicate that the site represents a new and interesting extension of Palaeolithic archaeology in the northwest of Arabia similar to Palaeolithic characteristics in the Jubbah basin. Thus, this discovery has a direct relevance in assessing the distribution of Palaeolithic sites in the Ha’il region, showing that they not only occur in the northern area (Nefud desert), but also in the different landscape (basaltic lava field) in the southern part of the region.

“…The first one was conducted between 1973 and 1975 by the Arabian Geophysical and Surveying Company (ARGAS), it was initiated to cover the entire Kingdom (Mogren, 2004). The second gravity campaign Miller et al, 1989;Mogren et al, 2013). The gravity surveys were adjusted and connected to the new absolute gravity station at KSU before using in the geoid calculation, more details are found in Mogren et al (2013).…”

A gravimetric geoid model (SAGEO13) is computed for the Kingdom of Saudi Arabia using a rigorous stochastic computational method. The computational methodology is based on a combination of least-squares (LS) modification of Stokes’ formula and the additive corrections for topographic, ellipsoidal, atmospheric, and downward continuation effects on the geoid solution. In this study, we used terrestrial gravity data, a digital elevation model (SRTM3), and seven global geopotential models (GGMs) to compute a new geoid model for Saudi Arabia. The least-squares coefficients are derived based on the optimisation of the input modification parameters. The gravimetric solution and its additive corrections are computed based on the optimum LS coefficients. Compared to GPS-levelling data, SAGEO13 shows a fit of 18 cm (RMS) after using a 4-parameter fitting model.
