Geological history of Point Lobos of waves and rain that cause erosion of the others type of rocks. The age of this kind of rocks varies from ten thousand years ago up to the present day. Geological history of Point Lobos The geological history of Point Lobos, regarding the Point Lobos headland on the Central Coast in Monterey County, California|Monterey County]], California. The area's geology encompasses the last 80 million years.

Partridge Island (Nova Scotia) geological period between 208 and 220 million years ago, rivers swollen by intense rains carried coarse sediments (now sedimentary rocks) from nearby highlands into the Fundy Basin. Other deposits came from wind-blown sand dunes. Later, large lakes formed on the central part of the basin depositing finer sediments up to 1,000 metres thick and, as they dried up periodically, they left behind salt and gypsum deposits. The red sedimentary sandstone base of Partridge Island dates from the late Triassic period. The covering layer of dark basalt was formed from magma and lava eruptions in the Jurassic period between 175 and
