3700 Geowilliams (1984 UL2) is a main-belt asteroid discovered on October 23, 1984 by Shoemaker, C. and Shoemaker, E. at Palomar. Named in honor of George E. Williams, exploration geologist with Broken Hill Proprietary Co., Ltd. at Adelaide, South Australia. Williams discovered the Lake Acraman impact structure of South Australia, the largest such feature found so far on the Australian continent. He also discovered rhythmically layered sedimentary deposits of Precambrian age that exhibit periods closely matching those of the modern solar cycle. == External links == *(JPL Small-Body Database Browser on 3700 Geowilliams ) 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「3700 Geowilliams」の詳細全文を読む スポンサード リンク
