The meteorite found in the Empty Quarter of Kingdom of Saudi Arabia (KSA) is the largest meteorite found in the KSA and has the shape of an irregular ellipsoid with semi-axes of 0.65 m, 0.38 m, and 0.27 m; a density of 6400 kg/m³; and a mass of 2550 kg. It is a massive piece belonging to the category of iron–nickel meteorites, which is contained in only 5% of the total showers. The present report is on the Elemental composition and physical characteristics of the massive meteorite of the saudi empty quarter employing with laser-induced break down spectroscopy (LIBS), X-ray fluorescence (XRF), scanning electron microscope (SEM), x-ray diffraction (XRD) and energy-dispersive x-ray spectrophotometry (EDX).

Present study has indicated that the meteorite is composed of about 5% Ni, 91% Fe, 1.51% P, 0.3% Co, and a host of other elements, most of them appeared as oxides. The measured density of the meteorite is 6400 kg/m³ and it is confirmed by the micro-hardness test that the meteorite is porous (approximately about 19%). Based on our investigation, it is very likely that this meteorite would have “escaped” from the belt around Mars and Jupiter and is unlikely from the moon or elsewhere. This could be the first such study, employing the advanced instruments mentioned above regarding massive Saudi meteorite.

在沙特阿拉伯王国空区（KSA）中发现的陨石是在KSA中发现的最大陨石，其形状为不规则椭圆形，半轴分别为0.65 m， 0.38 m和 0.27 m。密度为6400 kg / m ³ ; 重2550公斤 这是一块巨大的碎片，属于铁镍陨石类别，仅占总淋浴次数的5％。本报告是利用激光诱导击穿光谱法（LIBS），X射线荧光（XRF），扫描电子显微镜（SEM），X射线对沙特空区大块陨石的元素组成和物理特性的研究衍射（XRD）和能量色散X射线分光光度法（EDX）。

目前的研究表明，陨石由大约5％的Ni，91％的Fe，1.51％的P，0.3％的Co和许多其他元素组成，其中大多数以氧化物形式出现。测得的陨石密度为6400 kg / m ^3，并且通过显微硬度测试证实了该陨石是多孔的（约19％）。根据我们的调查，这种陨石很可能会从火星和木星周围的带中“逃脱”，而不太可能从月球或其他地方逃脱。这可能是第一个这样的研究，它使用上面提到的有关大规模沙特陨石的先进仪器。
