Ágrip SAGA SÍÐJÖKULTÍMARANNSÓKNA í NEÐRIHLUTA BORGARFJARÐARHÉRAÐS Ólafur Ingólfsson Háskólanum í Lundi Láglendi Borgarfjarðarhéraðs er víðast þakið setlögum frá síðjökultíma og nútíma. Fyrstur náttúrufræðinga til að kanna þessi setlög var Egg- ert Ólafsson um miðbik 18. aldar. Á 19. öld unnu m. a. Jónas Hallgrímsson, Pjóðverjinn Konrad Keilhack og Þorvaldur Thoroddsen að rannsókn- um í Borgarfirði. Þeir lýstu fundarstöðum forn- skelja, minjum um sjávarstöðubreytingar og um- merkjum jöklunar í héraðinu. Á 20. öld hafa fjölmargir jarðfræðingar ritað um síðjökultímajarðfræði svæðisins, en verið um fátt sammála. Yfirgripsmesta rannsóknin var gerð af Guðmundi G. Bárðarsyni sumarið 1920. Hann lýsti jarðlagaskipan setlaga víða um hér- áðið, og safnaði fornskeljum til greiningar. Hann greindi milli tveggja megin leireininga, sem víða JÖKULL 34. ÁR 129
