For each answer the following.
a. Describe a local hand.
specimen of the rock, particularly its texture and minerals, Explain its mode of formation,
Describe briefly the landscape it usually produces in Hong Kong and name an area in Hong
Kong where an example is found.
Suggested Answers:
11. Granite
a. Minerals and texture
Biotite
Glassy Quartz
Feldspar
HAND SPECIMEN OF. A GRANITE
Granite is mainly composed of quartz, which is glassy or white in colour, feldspar (orthoclase), which is white or pink in colour;
and biotite, which is black in colour. Granite is a kind of medium granined rock, with crystals around 1-3mm in size.
b. Mode of Formation
Granite if a kind of plutonic igneous rock which is formed by the solidification of magma when it is cooled. It usually occurs in large masses or batholiths, at a great distance below the surface. When the overlying Trucks have been eroded, granite exposes on the suface.
c. Landscapes
Under the humid and hot. climate in Hong Kong, granite is a kind of weak rock which weathers very easily, so it always forms lowlands or Tow hill, below 300M.
the Castle Peak Hills, the range of hills to the north of Kowloon and N Lantao. Sometimes, serious erosion acts on granite and badland is formed. The surface is bare of any vegetation cover, such as in the Castle Peak region.
Conglomerate
a. Minerals and Texture
Coarse: ground
mass
Quartz pebbles
HAND SPECIMEN OF A TYPICAL CONGLOMERATE
Conglomerate is coarsed grained. It consists of rounded pebbles which are cemented together by finer materials, in a red or brow groundmass, 200
b. Mode of Formation
It is a type of mechanically formed sedimentary rock, for. formed along the former sea coast. It is resulted from the
position of materials derived
from the weathering and erosion of other rocks, c. Landscapes
Conglomerate is usually resistant and therefore forms a cap rock to ridges, e.g. the Pat Sin Range, 12.

The above table shows the climatic data and rock types of 5 different locations. Which one do you think experiences the most active chemical weathering? Give reasons to support
your answer.
Suggested Answers: 12: The granite found af
location E experiences the most active chemical weathering,
The rate of chemical weathering is determined not only by the resistance of rock but also by temperatures, amount of rainfall and distribution of rainfall.
Chemical weathering takes place mest rapidly. in regions of humid climates, with high temperatures, or”. regions where the rainfall is
highly irregular. The high temperature (31°C in July) heavy annual rainfall (2000 mm) with a great.
concentration in summer.
(1600mm). at location E thus favour chemical weathering.
The rapid rate of chemical weathering at location E also aided by the nonstance nature of granite. Amongst the four differnet types of rocks, granite is the one that is the most susceptible to chemical weathering. It is elatively less resistant under the above climatic condition.
Owing to the high temperatures and heavy rainfall, chemical process such as hydration hydrolysis, carbonation and oxidation take place in the rock. These are not only on the surface as rain water penetrates well below the surface along joints and cracks. Granite is a kind of well-jointed, coarsed grained crystalline rock composed of micay - feldspar and quartz, The mica weathers the fastest and in doing so produces. iron oxide. The feldspar decomposes slowly, and it combines with water to form a fine clay, sometimes known as kaolin. Following decomposition, the
resultant clay is washed out and the rock structure is weakened. Coupled with this there is a considerable breakdown of the resistant silica or quartz. This can be partly explained by the periodic rains, followed by a rapid dessication of the rock which results from high insolation. As a result of the stresses and a strains caused by these chemical actions the granite decays and breaks up.
For location D, although the climatic condition is th same, rhyolite, a kind of fine grained volcanic rock, is much more resistant than; granite.
For location A, despite the non-resistant nature of, shale and the hot summer, the dry condition in that season does not favour active chemical weathering
For both B and C, temperatures are cool, annual rainfall is moderate and summer rainfall is. scanty, such a climatic condition does not favour rapid chemical weathering too.
