The technic mod makes extensive use of not just the default ores but also
some that are added by mods. You will need to mine for all the ore types
in the course of the game. Each ore type is found at a specific range of
-altitudes, and while the ranges mostly overlap, some have non-overlapping
-ranges, so you will ultimately need to mine at more than one altitude
-to find all the ores. Also, because one of the best altitudes to mine
+elevations, and while the ranges mostly overlap, some have non-overlapping
+ranges, so you will ultimately need to mine at more than one elevation
+to find all the ores. Also, because one of the best elevations to mine
at is very deep, you will be unable to mine there early in the game.
+Elevation is measured in metres, relative to a reference plane that
+is not quite sea level. (The standard sea level is at an elevation
+of about +1.4.) Positive elevations are above the reference plane and
+negative elevations below. Because elevations are always described this
+way round, greater numbers when higher, we avoid the word "depth".

The ores that matter in technic are coal, iron, copper, tin, zinc,
chromium, uranium, silver, gold, mithril, mese, and diamond.
-Coal is part of the basic Minetest game. It is found from altitude
-+64 downwards, so is available right on the surface at the start of the
-game, but it is far less abundant above altitude 0 than below. It is

+It is initially used as a fuel, driving important machines in the early
+part of the game. It becomes less important as a fuel once most of your
machines are electrically powered, but burning fuel remains a way to
generate electrical power. Coal is also used, usually in dust form, as
an ingredient in alloying recipes, wherever elemental carbon is required.
-Iron is part of the basic Minetest game. It is found from altitude
+Iron is part of the basic Minetest game. It is found from elevation
+2 downwards, and its abundance increases in stages as one descends,
-reaching its maximum from altitude -64 downwards. It is a common metal,
+reaching its maximum from elevation -64 downwards. It is a common metal,
used frequently as a structural component. In technic, unlike the basic
game, iron is used in multiple forms, mainly alloys based on iron and
including carbon (coal).
Copper is part of the basic Minetest game (having migrated there from
-moreores). It is found from altitude -16 downwards, but is more abundant
-from altitude -64 downwards. It is a common metal, used either on its

+from elevation -64 downwards. It is a common metal, used either on its
own for its electrical conductivity, or as the base component of alloys.
Although common, it is very heavily used, and most of the time it will
be the material that most limits your activity.
-Tin is supplied by the moreores mod. It is found from altitude +8

+Tin is supplied by the moreores mod. It is found from elevation +8
+downwards, with no elevation-dependent variations in abundance beyond
that point. It is a common metal. Its main use in pure form is as a
component of electrical batteries. Apart from that its main purpose is
as the secondary ingredient in bronze (the base being copper), but bronze
is itself little used. Its abundance is well in excess of its usage,
so you will usually have a surplus of it.
-Zinc is supplied by technic. It is found from altitude +2 downwards, with
-no altitude-dependent variations in abundance beyond that point. It is
-a common metal. Its main use is as the secondary ingredient in brass

+to -300; using it therefore requires one to mine above elevation -300 even
though deeper mining is otherwise more productive. It is a moderately
common metal, useful only for reasons related to radioactivity: it forms
the fuel for nuclear reactors, and is also one of the best radiation

It is safe when more than a metre away or when mined.

+Silver is supplied by the moreores mod. It is found from elevation -2
+downwards, with no elevation-dependent variations in abundance beyond
that point. It is a semi-precious metal. It is little used, being most
notably used in electrical items due to its conductivity, being the best
conductor of all the pure elements.
Gold is part of the basic Minetest game (having migrated there from
-moreores). It is found from altitude -64 downwards, but is more abundant
-from altitude -256 downwards. It is a precious metal. It is little used,
-being most notably used in electrical items due to its combination of
-good conductivity (third best of all the pure elements) and corrosion
-resistance.

-Mithril is supplied by the moreores mod. It is found from altitude
--512 downwards, the deepest ceiling of any minable substance, with no
-altitude-dependent variations in abundance beyond that point. It is a
-rare precious metal, and unlike all the other metals described here it
-is entirely fictional, being derived from J. R. R. Tolkien's Middle-Earth
-setting. It is little used.

--64 downwards. The ore is more abundant from altitude -256 downwards,

some magical quality needs to be imparted.
