 Nyorai kupfuurira kweiyi ndima - Deep sea core samples yakawana anenge 10 marine isotope nhanho zvirinani MIS 21 kusvika MIS 11 panguva yeGunz. Nokudaro, zvichida kwave kune kutenderera kwechando kunenge 5 kwokusimba kwakasiana-siana mukati meGunz. Mukati meGunz kutenderera kwechando kwemakore 41 000 ematanho apfuura Biber neDanube kwakanga kwatsiviwa nekutonga kwedenderedzwa remakore 100 000 Mid-Pleistocene Transition. Mazera echando akakura zvikuru eGunz MIS 16 neMIS 12 akasvika pakukura kwakafanana neaya eRissuye Wurm glacials. Izvozvi hazvina kuva nyore kuziva muzvinyorwa zve geological zveAlps, asi MIS 16 yakabatanidzwa neDon Glaciation yeEastern Europe. Nguva yechando yakasimba yeMIS 12 yave ichinetsa, uye dzimwe nguva yave ichifananidzwa neMindel glaciation, izvo zvaizoreva kuguma kweGunz kare mushure meMIS 13 480 000 makore apfuura.
