 Changes: A Quaternary Example from the Tenryugawa Fan System, Pacific Coast 

 of Central Japan," Journal of Geology . Vol 95, pp 716-724. 



A new hypothesis for dynamic processes in coastal fans is presented, 

 based on the concepts of temporal changes in fan morphology and associated 

 sediment bodies in phased and cyclic mode. These changes, which are marked by 

 overflows from a "fan valley" before its complete burial as well as after the 

 initiation of its entrenchment, are entirely related to relative sea-level 

 changes. The hypotheses is exemplified by the Middle Pleistocene to Holocene 

 Tenryugawa fan system, Pacific coast of central Japan. (Author).

 Island, California," Quaternary Research . Vol 20, pp 322-341. 



Global sea- level changes are expressed in the coastal landforms and 

 deposits of northern San Clemente Island. Stratigraphic , radiometric, amino 

 acid and pedologic dating techniques have allowed the development of a chrono- 

 logy of sea- level changes for about the last 500,000 year. A uranium- series 

 date on coral of about 127,000 year for the 2nd terrace serves as a 

 calibration point for amino acid age estimates of four other mapped terraces. 

 Two of these terraces have age estimates of about 80,000-105,000 year, another 

 has an age estimate of about 127,000 year, and the 5th terrace on the west 

 side of the island is estimated to be about 415,000-575,000 year old. These 

 dates correlates reasonably well with marine terraces dated elsewhere and with 

 stages of the oxygen- isotope record that are thought to represent high stands 

 of the sea. Weakly cemented calcareous dune sands (eolianites) are moderately 

 extensive on northern San Clemente Island and appear to represent low stands 

 of the sea, since calcareous shelf sands were the most likely source. A 

 radiocarbon date of about 22,000 year suggests that the youngest eolianite was 

 deposited during the last glacial maximum. An older eolianite is estimated to 

 be about 140,000-195,000 year old based on stratigraphic relations and degree 

 of soil development. The suggested ages for the eolianites also correlate 

 well with oxygen- isotope estimates of low sea-levels. (Author). 



231 MUHS, D. R. 1985. "Amino Acid Age Estimates of Marine Terraces and 

 Sea-Levels on San Nicolas Island, California," Geology . Vol 13, pp 58-61. 



Fourteen marine terraces rising to an elevation 274 m have been mapped 

 on San Nicolas Island, California. The lowest terrace is -105,000 years old, 

 on the basis of amino acid ratios in fossil mollusks slightly lower than those 

 from the -120,000 year old, uranium- series dated second terrace. The age 

 estimate and present elevation of the lowest terrace, along with an assumption 

 of constant uplift rate, indicate a paleo-sea-level estimate of -10 to -12 m 

 at about 105,000 B.P., supporting the general Barbados model of sea-level 

 history. The fourth and fifth terraces probably represent separate high sea- 

 level stands during the same interglacial complex >400,000 B.P. The eight and 

 tenth terraces have amino acid ratios near equilibrium and imply ages of
