Ancient DNA in smectites – microdiffraction and micromorphology

Ancient sedimentary DNA (sedaDNA) is transforming archaeology but its reliability hinges on its preservation within sediments. Smectite clays are crucial: they intercalate DNA...古沉积物DNA（sedaDNA）正重塑考古学研究范式，但其可靠性高度取决于其在沉积物中的保存状态。蒙脱石粘土（smectite clays）在此领域至关重要：它们可与DNA发生插层结合……
