|Comments||Before landing on Port Island, you will see that island mostly covered by reddish stones. The unflated surface on the island appears like planet’s surface. There are steep route to Chek Chau Cave, we have only took a far view to the cave but climbed up to Chek Chau Teng. At the top there is a splendid view of Wong Chuk Kok Tsui, and looked at the mountain’s foot, the reddish island’s view is also beautiful.|

After more than 6 million years of robust lava and volcanic activities, most regions of Hong Kong became igneous rock terrains. When volcanic activities subsided, extended dry climate set in. Great temperature difference between day and night caused avalanches. Weathered rocks toppled down from the uplands and were quickly transported and deposited. Gravel, sand and silt arising from weathering were washed down by seasonal rainstorms to the alluvial plains where they settled. There, the ferric minerals within turned into iron oxide and bonded sand and other sediments to become a unique red sedimentary rock. Hot climate and the scorching sun aided release of iron in the sand and gravel. For this reason they were tinted red or rust in various intensities. Sediments of the alluvial plains and river channels eventually formed the red or coloured terrestrial clastic sedimentary rocks seen on Port Island today. Main components are conglomerate, sandstone and siltstone. These rocks are known as Port Island Formation.
