 American . Vol 247, No. 2, pp 36-43. 



Three issues of carbon dioxide effects are examined in this paper: 



(1) how much and at what rate carbon dioxide will be added to the atmosphere, 



(2) what the global rise in temperature would be in the various regions, and 



(3) the human impact of increased concentrations of carbon dioxide and other 

 trace gases. (Gorman). 



293 RHEA, S. 1989. "Evidence of Uplift Near Charleston, South Carolina," 

 Geology . Vol 17, pp 311-315. 



In spite of extensive research, the causal structure of the 1886 

 magnitude 7 earthquake near Charleston, South Carolina, has not been 

 identified. In this study, I analyzed digital surface topography and river 

 morphology in light of earlier studies using seismic reflection, seismic 

 refraction, earthquake seismology, and gravity and magnetic surveys. This 

 analysis revealed and area approximately 400 km^ northwest of Charleston that 

 may have been repeatedly uplifted by earthquakes. Geologic and seismic 

 reflection data confirm alteration of formations at depth. Deformation of the 

 surface is supported by observations on aerial and LANDSAT photographs. 

 Therefore, the structure on which the 1886 earthquake occurred may be within 

 the uplifted area defined in this report. (Author). 



294 RICHARDS, G. W. 1985. "Fossil Mediterranean Mollusks as Sea-Level 

 Indicators," Geological Magazine . Vol 122, No. 4, pp 373-381. 



Intertidal mollusks are known to occur in similar positions or zones on 

 shores throughout the world. However, little is known about the extent to 

 which these distributions are preserved in the fossil record. This study 

 attempts to define the relationship to present sea-level of live and dead 

 intertidal mollusks in the Mediterranean, and utilizes this information to 

 interpret the position at which Quaternary shorelines were formed. 



The preservation of zonation patterns in the fossil record is affected 

 by post-mortem transport, breakage and burial of the shell material. To take 

 account of such taphonomic changes, experimental studies of shell transport 

 and burial under waves and unidirectional currents were made, and the distri- 

 bution of dead mollusks on modern shores were compared with live distribu- 

 tions. It proved possible to predict the frequency with which certain species 

 were deposited on the modern shore and, by analogy, the likelihood of their 

 preservation in the fossil record. Thus death assemblages in fossil shore- 

 lines can be accurately related to past sea-levels. (Author).
