• Aggregates are broadly a category of coarse
  particulate material including sand, gravel,
  crushed stone, slag, recycled concrete and
  geosynthetic aggregates.

• Aggregates are the most mined materials in the
  world and while a lot of agregates are used for
  their physical properties like concrete or
  btichemum aggregates other like the Yuleba
  aggregates are decorative. The Yuleba aggregates
  have a gemstone quality are uncrushed and have
  been widely used for exposed concrete surfaces
  and landscaping.

• Due to the relatively high hydraulic conductivity
  value as compared to most soils, aggregates are
  widely used in drainage applications such as
  foundation and French drains, septic drain
  fields, retaining wall drains, and road side edge
  drains.

• Aggregates are also used as base material under
  foundations, roads, and railroads. In other
  words, aggregates are used as a stable foundation
  or road/rail base with predictable, uniform
  properties (e.g. to help prevent differential
  settling under the road or building), or as a
  low-cost extender that binds with more expensive
  cement or asphalt to form concrete.

• The Yuleba deposit has Petrified wood literally
  "wood turned into stone" is the name given to a
  special type of fossilized remains of terrestrial
  vegetation. It is the result of a tree or
  tree-like plants having completely transitioned
  to stone by the process of permineralization.

• All the organic materials have been replaced with
  minerals(mostly a silicate, such as quartz),
  while retaining the original structure of the
  stem tissue. Unlike other types of fossils which
  are typically impressions or compressions,
  petrified wood is a three-dimensional
  representation of the original organic material.

• While petrified wood is found around Roma, Surat
  and Chinchilla is quite large in size TheYuleba
  petrified wood while generally ranging in size
  from a few mm in size and typically 20mm but
  often as large as 200mm has a very high silica
  contentent and can be easily cut and polished.

• Aggregates like those found in the Yuleba depsoit
  which are high in silica content have both good
  aesthetic and physical properties making them
  ideal for exposed aggregate concrete or
  decorative applications. The naturally rounded
  shapes minimise sharp edges found in crushed
  aggregates.
