Sedimentological and Geochemical Analysis of the Upper Paleozoic Sedimentary Sequences in Kinta Valley, Peninsular Malaysia

The palaeozoic sequence stratigraphic position and geological age of the Kinta Valley limestone and associated clastics are not well understood. Subjection to diagenetic and metamorphic alterations increases the difficulties in the application of sedimentological study. Geochemical results show...

description The palaeozoic sequence stratigraphic position and geological age of the Kinta Valley limestone and associated clastics are not well understood.
