  Microlith - Wikipedia, the free encyclopedia
Microliths were either produced from small blades (microblades) or made by snapping normal big blades in a controlled manner, which leaves a very typical piece of waste (microburin).
Some types of microliths, such as trapezes, were used in the Neolithic as well (the Linear Pottery culture and Funnelbeaker culture).
Microliths were produced during the middle stone age (Mesolithic), in a period which is in some areas denoted as the epipalaeolithic.

For the purposes of this invention, the terms "microlith" and "microlith catalyst" refer to high open area monolith catalyst elements with flow paths so short that reaction rate per unit length per channel is at least fifty percent higher than for the same diameter channel with a fully developed boundary layer in laminar flow, i.e.
Microlith catalysts may be in the form of woven wire screens, pressed metal or ceramic wire screens or even pressed thin ceramic plates and have as many as 100 to 1000 or more flow channels per square centimeter.
Microlith catalyst elements 21 having 400 flow channels per square centimeter are spaced apart a distance equal to or greater than the length of the flow paths 22 to provide for some mixing of gases flowing between elements 21.

Epipalaeolithic hunter-gatherers made relatively advanced tools made from small flint or obsidian blades, known as microliths that were hafted in wooden implements.
The period between the end of the last ice age, 10,000 years ago to around 6,000 years ago, is characterised by rising sea levels and a need to adapt to a changing environment and find new food sources.
Tiny microliths constituted the edges of bone daggers that were often decorated with geometric patterns.

 Catalytic method - Patent 5342591
It has been found that a metal microlith composed of a high temperature alloy containing a catalytic element such as chromium, cobalt, copper, manganese, nickel or a rare earth metal is catalytically active if heated to a temperature of about 800 degrees Kelvin, a temperature readily achieved in less than one second with electrical heating.
In particular, microlith catalysts offer superior performance in highly exothermic reactions such as the conversion of methane and other hydrocarbons to partially oxidized species such as the conversion of methane to methanol or and the conversion of ethane to ethylene.
An microlith catalyst as per figure one is made by vacuum sputtering platinum onto a stainless steel screen which has been cleaned by heating in air to 750 K. Typically the platinum coating may be thinner than 100 angstroms but may be thicker for greater catalyst life.

The blades are largely narrow, which agrees well with the microlithic armatures based on narrow blades.
The two microlithic armatures are also based on narrow-blades (28, 29), and therefore these diagnostic tools agree with the material in the remainder of the assemblage.
The narrow blade microlithic armatures suggests that this assemblage belongs to the Late Mesolithic.

They were shaped by abrupt retouch into various shapes like triangles and crescents.
Microliths were produced during the Later Upper Palaeolithic and Mesolithic and were either struck as blades from very small cores or were made from fractured blades using the microburin technique.
Microliths represent both a versatile and an economic use of raw material: just as blades yield more cutting edge than flakes per unit weight of raw material, so bladelets improve yet further this advantage, by a factor of something over 100 compared to core tools.

Research is needed to investigate microlith tool function with the aim of distinguishing domestic and hunting activities.
Research into microlith function will initiate with a revision of ethnographic literature, particularly relating to small tool traditions, followed by the examination of relevant ethnographic and archaeological collections in museums across Europe.
Samples of microliths will be taken from major sites across the UK including Star Carr (regarded as one of the most important Mesolithic sites in Europe) for analysis.
