Preheat oven to 350 degrees F (175 degrees C). In a medium skillet over medium heat, brown the ground beef; drain fat. In a medium mixing bowl, combine cream of mushroom soup, onion, milk, salt and pepper to taste. Alternately layer the potatoes, soup mixture and meat in a 11x7 inch (2 quart) baking dish. Bake in the preheated oven for 1 to 1 1/2 hours, or until potatoes are tender.
By definition, basalt is an aphanitic igneous rock with less than 20% quartz and less than 10% feldspathoid by volume, and where at least 65% of the feldspar is in the form of plagioclase.Basalt features a glassy matrix interspersed with minerals.asalt is one of the most common rock types in the world. Basalt is the rock most typical of large igneous provinces. The largest occurrences of basalt are in the ocean floor that is almost completely made up by basalt.
  Basaltic magma is low in silica and rich in iron and magnesium. It  is denser, more fluid, and hotte â¦ r than most other types of magma.  Because of its generally low gas content, volcanic eruptions  involving it are typically non-explosive or only mildly explosive,  often resulting in rivers of red hot lava.It is less dense, more viscous, and cooler than most other types of  magma. It usually has a very high gas content, meaning that most  eruptions involving it will be highly explosive. Most  supervolcanoes are fed by rhyolitic magma.
