Taking the Late Mesozoic basic-intermediate dike swarms from this area as the main object, we have studied their Petrology, Geochemistry and Isotopic Chronology, and discussed the property of their magmatic source, tectonic setting and origin as well. The significant conclusions acquired are as follows: 1, The Late Mesozoic dike from the coastland of Fujian Province appears as clusters, intruding into the Late Mesozoic granite or volcanic rocks, and the lithologies are diabase, hornblende diabase and quartz-diorite etc, mainly diabase. The mode of their occurrence is mainly precipitous and they tend towards NE, approximately EW or NNE. The dike swarms did not suffer metamorphose or distortion, holding the stress state as the dike formed.

The SiO2 content of the dike swarms varies from 50.22% to 61.10% and they are basic-intermediate rock series, mainly basic. The Al2O3 content is generally higher than 15% and they are high aluminum basaltic rocks. The lower magnesium index (Mg#=42.77~62.28) and TiO2 content (0.97~2.41%) illuminate that they suffered magnesium-iron minerals' fractional crystallization and that they did not crystallize from original basaltic magma. The values of Na2O/K2O are all above 1, indicating lower K character. Chemically discriminated, these dike swarms are sub-alkaline rock series.
