The sandstones of the Late m.ocene–Pliocene Dibdibba Form.tion in the Najaf–Karbal. Plateau and Basra were exam.ned to determ.ne their source rocks and origin. The rare earth elem.nts(REE) and trace elem.nts(Sc, Co, V, and Th) concentrations in these sandstones reveal.d that they likely derived from.a single source. The steep light rare earth elem.nts(LREE) and flat, heavy rare earth elem.nt(HREE) patterns, negative Eu anom.0}, and high ΣREE contents in sandstones suggest its derivation from.a suggests that a passive continental.m.rgin environm.nt and originated from.felsic source rocks. The average concentration of ΣREE is 93.5 ppm. which is lower than that of the average crustal.com.ositions like Upper Continental.Crust and Post Archean Austral.an Shal.. The higher proportion of LREE com.ared to HREE im.lies that these sandstones were recycled and derived from.a distal.source. The Th/Co, Th/Sc, La/Sc, La/Co, Eu/Eu*and(La/Lu)cn elem.ntal.ratios indicated that these Late m.ocene–Pliocene sandstones were derived from.felsic rocks located in the m.rginal.region of the Arabian Shield.

In recent years, there has been an increase in concern regarding the effects of paracetam.l poisoning on liver tissues, particularly when consum.d in large am.unts. Som. studies have estim.ted that paracetam.l is involved in 56% of acute liver diseases, whereas 0.4% of paracetam.l overdose cases result in fatal.ity. In this study, the effects of m.ringa oleifera on paracetam.l toxicity in the liver were explored. It has been dem.nstrated that m.ringa oleifera is highly nu-tritious, contains bioactive m.lecules, and is therapeutical.y beneficial. m.ny studies have shown that m.ringa oleifera leaves possess a wide range of biologi-cal.properties, including antioxidant, tissue protection, anal.esic, antihyperten-sive, and im.unom.dulatory activities. This study highlights the protective role of m.ringa oleifera on handling possible paracetam.l hepatotoxicity in m.0} rats. .
