This research describes the qualities and distributions of several ions in groundwater in Buriram province, as well as the influences of inactive volcanoes on groundwater. The contents of dissolved calcium (Ca²⁺), sulfate (SO₄²⁻), magnesium (Mg²⁺), chloride (Cl⁻), sodium (Na⁺), iron (Fe²⁺), and groundwater table were analyzed from 2891 groundwater wells. The relationships of the laying rock and groundwater associated with high ion concentrations that all ions except iron are more related to the Mahasarakham formation. High spatial distributions are shown at the lowermost middle to the upper province by the weathering processes of halite (NaCl), anhydrite (CaSO₄), and carnallite (KMgCl₃·6H₂O). Then the iron is interrelated with the Phra Wihan, Sao Khua, and Phu Phan formations that moderately high iron has dissolved and supplied to groundwater, as shown in the lowermost province. In contrast, other high-iron concentrations of the western lower, middle-lower, and upper-middle provinces conform with inactive volcano distributions of an unnamed hill, Phu Angkarn and Khao Phanom Rung hills, and Khao Kradong hill. They consist mainly of olivine ((FeMg)₂SiO₄), fayalite (Fe₂SiO₄), forsterite (Mg₂SiO₄), iddingsite (MgFe₂Si₃O₁₀•4(H₂O)), and plagioclase (CaAl₂Si₂O₈). That iron will gradually increase depending on the alteration degree of olivine to fayalite, iddingsite, and laihunite (Fe²⁺Fe³⁺2(SiO₄)₂) that is higher around inactive volcanoes. Next, the dissolved calcium and magnesium are produced by the alteration of plagioclase and olivine; however, their distributions are lower relative to volcanic rock than evaporite. Lastly, high spatial concentrations of iron at lower upper provinces are not associated with inactive volcanoes that they are the results of iron accumulation and transportation along with flow directions from inactive volcanoes and lowermost mountain range.

这项研究描述了武里南省地下水中几种离子的质量和分布，以及不活动的火山对地下水的影响。分析了溶解钙（Ca ²⁺）、硫酸盐（SO ₄ ^2-）、镁（Mg ²⁺）、氯化物（Cl ^-）、钠（Na ⁺）、铁（Fe ²⁺）和地下水位的含量来自 2891 个地下水井。与高离子浓度相关的岩层和地下水的关系，除铁之外的所有离子都与 Mahasarakham 地层相关。岩盐 (NaCl)、硬石膏 (CaSO₄ )，和光卤石(KMgCl ₃ ·6H ₂ O)。然后，铁与 Phra Wihan、Sao Khua 和 Phu Phan 地层相互关联，这些地层中的铁含量中等，已溶解并供应到地下水中，如最下方的省份所示。相比之下，西部低、中、中上省的其他高铁浓度符合无名山、Phu Angkarn 和 Khao Phanom Rung 山以及 Khao Kradong 山的非活动火山分布。它们主要由橄榄石（(FeMg) ₂ SiO ₄）、铁橄榄石（Fe ₂ SiO ₄）、镁橄榄石（Mg ₂ SiO ₄）、镁橄榄石（MgFe ₂ Si ₃ O₁₀ •4(H ₂ O)) 和斜长石（CaAl ₂ Si ₂ O ₈）。铁会随着橄榄石向铁橄榄石、艾丁石和莱茵石(Fe ²⁺ Fe ³⁺ 2(SiO ₄ ) ₂的蚀变程度而逐渐增加)) 在不活动的火山周围更高。其次，溶解的钙和镁是由斜长石和橄榄石的蚀变产生的；然而，相对于火山岩，它们的分布低于蒸发岩。最后，上下游省份铁的高空间浓度与非活动火山无关，它们是铁积累和运输以及来自非活动火山和最低山脉的流动方向的结果。
