9) Recent experimental data on the melting and phase transformations of iron and
nickel to pressures provide important information to understand the nature of the
earth’s solid inner core and liquid outer core.
10) Phase transformations study of minerals from pelagic ferro-manganese nodules
was conducted in three directions: a) characterizing of matter from different growth
zones of nodules; b) high temperature heating in dry air; c) experimental modelling
metamorphic processes at high temperatures and pressures in at high temperatures
and pressures in different media.
The Infinitive
1) Large amounts of energy are necessary to deform rocks, generate magma, and
cause metarmorphism.
2) The heat flow from the earth indicates the presence of sources of heat energy large
enough to account for geologic processes.
3) There are several different kinds of measurements to be taken, which express
important facts.
4) Our scientists were the first to synthesize diamonds.
5) To have any deposition there must exist a source of sediments.
6) The factors controlling this process are difficult to visualize.
7) Radioactivity energy is enough to cause all geological processes.
8) To finally recover the gold it is only necessary to scrape off the sludge of mercury
and gold and refine it.
9) A true hypothesis will prove to be in harmony with newly discovered facts.
10) Hydrochemical prospecting to be described in the article has been used for
finding uranium, molybdenum, zinc and copper deposits.
11) Geochemical methods are applied at different stages of geological investigations,
and are used to establish the general mineralization of rocks (i.e. the areas of
increased concentration of particular elements).
12) To detect such concealed deposits as coal, shale, iron, manganese, salts and
others is very difficult.
13) The geological and physical conditions of the seam to be worked include its
thickness, depth, hardness, etc.
14) To determine both the shape and the size of a deposit it is very important to
establish its structure.
The Complex Subject
1) Open cast mining seems to be the most productive system.
2) Extensive deposits of phosphatic sediments are known to exist off the coasts of the
south-eastern United States.
3) The core is believed to be mainly molten iron with some nickel.
4) Bronze is thought to have been used by the ancients.
5) Convection is believed to be an important process in the mantle.
