摘要：

This paper examines the results of R-mode factor analysis performed on major ion data from a hydrogeochemical survey over the coastal Quaternary deltaic aquifer of the Cauvery Basin, Tamil Nadu, India. Seven major ions (Ca, Mg, Na, K, HCO3, Cl, and NO3) were analyzed from each of the 126 water samples collected in two seasons (pre- and post-monsoon 63 each). A set of factors was found both in pre-monsoon and post-monsoon data which explained the source of the dissolved ions and the chemical processes which accompany the intrusion of seawater.
