Gneiss does not have any particular mineral composition, and the term refers only to the banded texture. However, it only forms from igneous rocks and so tends to contain minerals not found in metamorphic rocks formed from sedimentary rock, such as marble. Despite the general appearance of banding, the distinct structures are elongated granular structures, so unlike schist, gneiss does not cleave along its bands.
Report Abuse If you sell your house and just live in your RV, then you save even more money. The cost per road trip can be a huge negative figure. Say you sell the house for $300K and buy a nice RV for $100K, you save $200K. Do only one roadtrip in your life, and the cost will be -$200K! Even after you subtract RV park fees and fuel, it's still $190+K in the pocket.
In considering costs and revenue, we can look also at a high speed line. In this example, the project is a 350 km line which is expected to cost US$ 17.5 billion to build and equip.Daily trips are expected to be 250,000, so each trip must generate $19.75 just to cover interest payments.t might cost US$ 50 million a kilometre including trains and all equipment necessary to run the line-power, signalling control, communications, fare collection, a maintenance depot, stations and operating offices. It could add up to US$ 750 million.
