What type of rock is tillite.
A tillite is a glacial till that has undergone the lithification process and has become a solid rock. The lithification process occurred because of the high pressures associated with burial and tectonics over the years. Location of the Huronian Supergroup, which includes rocks of the Gowganda Formation.
Here, Tillite is a clastic sedimentary rock, formed by the burial and hardening of a glacial till.

Conglomerate is a clastic sedimentary rock made up of rounded clasts that are greater than two millimeters in diameter. The spaces between the clasts are generally filled with sand- and clay-size particles. The rock is bound together by a cement that is usually composed of calcite or quartz. The Falklands’ rock succession. The Falkland Islands are made up of two main components, East and West Falkland, a dozen or so largish, subsidiary islands, and a myriad of smaller islands, rocks and reefs. These all add up to a total land area of just over 12,000km 2, though the islands are spread out over an area about twice that.

Sedimentary Rocks. Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water. These particles and chemicals come from the weathering (breaking apart in place) and erosion (carrying away and breaking apart while moving) of rocks on the Earth’s surface.
