The results are compatible with the high albedo (brightness) of Mercury's surface at visible wavelengths in suggesting a rock and soil composition that is devoid of basalt, the primary differentiate of terrestrial mantles. The occurrence of a basalt-free, highly differentiated crust is in accord with recent models of the planet's thermal evolution and suggests that Mercury has retained a hot interior as a result of a combination of inefficient mantle convection and minimal volcanic heat loss.\n          <\/jats:p>","DOI":"10.1126\/science.7770770","type":"journal-article","created":{"date-parts":[[2006,10,27]],"date-time":"2006-10-27T18:19:42Z","timestamp":1161973182000},"page":"1455-1457","source":"Crossref","is-referenced-by-count":84,"title":["Evidence for a Basalt-Free Surface on Mercury and Implications for Internal Heat"],"prefix":"10.1126","volume":"268","author":[{"given":"Raymond","family":"Jeanloz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David L.","family":"Mitchell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ann L.","family":"Sprague","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Imke","family":"de Pater","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"221","reference":[{"key":"e_1_2_1_1_1","unstructured":"Basaltic Volcanism Study Project Basaltic Volcanism on the Terrestrial Planets (1981)."},{"key":"e_1_2_1_2_1","doi-asserted-by":"crossref","first-page":"516","DOI":"10.1016\/0019-1035(88)90118-2","volume":"74","year":"1988","unstructured":"BENZ, W, COLLISIONAL STRIPPING OF MERCURYS MANTLE, ICARUS 74: 516 (1988).","journal-title":"ICARUS"},{"key":"e_1_2_1_3_1","first-page":"692","year":"1988","unstructured":"Cameron, A.
