Various kinds of rocks can be used as building stones based on their durability, appearance, and availability. During many periods of times, particularly the Hellenistic, tufa rocks were used as building stones because of their appropriateness for construction. In this research, tufa rocks exposed at Kurkur Oasis are evaluated based on various geological, petrophysical, and geomechanical investigations on 47 rock samples collected from four sites in the study area. Mineralogically, the studied tufa consists essentially of calcite with slight amounts of other minerals such as quartz, dolomite, gypsum, halite, and clay minerals. The tufa rocks are characterized by heterogeneous petrophysical and elastic properties. Porosity, density, and the geomechanical properties vary widely based on different facies and diagenetic processes. Major geomechanical differences between the studied rocks give constraints on the use of these rocks as bedrock foundation, or as construction and building stones. The obtained results and correlations between the different parameters help to predict the geomechanical properties from the more easily measured elastic and petrophysical parameters. Although the uses of tufa as an ornamental stones may be productive to the national economy, however, it is suggested that processing the tufa into polished, ornamental stone, cladding, tiles, and face slabs will be of more economical value both to the investors and the national economy especially at this time of economic stagnation.

根据其耐用性，外观和可用性，可以将各种岩石用作建筑石材。在许多时期，特别是希腊化时期，由于使用了适当的结构，因此使用了石灰石作为建筑石材。在这项研究中，根据对从研究区域四个地点采集的47个岩石样品进行的各种地质​​，岩石物理和地质力学研究，对暴露于库尔库尔绿洲的石灰石岩石进行了评估。从矿物学上讲，研究的石灰石主要由方解石和少量其他矿物组成，例如石英，白云石，石膏，盐石和粘土矿物。凝灰岩岩石具有非均质的岩石物理和弹性特性。孔隙度，密度和地质力学性质会因相和成岩作用的不同而有很大差异。被研究岩石之间的主要地质力学差异限制了这些岩石作为基岩基础或建筑石料的用途。获得的结果以及不同参数之间的相关性有助于根据更容易测量的弹性和岩石物理参数来预测地质力学特性。尽管使用石灰石作为装饰性石材可能会给国民经济带来收益，但是，建议将石灰石加工成抛光的装饰性石材，覆层，瓷砖和面板，对投资者和投资者都将更具经济价值。国民经济，特别是在经济停滞的时候。获得的结果以及不同参数之间的相关性有助于根据更容易测量的弹性和岩石物理参数来预测地质力学特性。尽管使用石灰石作为装饰性石材可能会给国民经济带来收益，但是，建议将石灰石加工成抛光的装饰性石材，覆层，瓷砖和面板，对投资者和投资者都将更具经济价值。国民经济，特别是在经济停滞的时候。获得的结果以及不同参数之间的相关性有助于根据更容易测量的弹性和岩石物理参数来预测地质力学特性。尽管使用石灰石作为装饰性石材可能会给国民经济带来收益，但是，建议将石灰石加工成抛光的装饰性石材，覆层，瓷砖和面板，对投资者和投资者都将更具经济价值。国民经济，特别是在经济停滞的时候。
