INTRODUCTION
This field record will cover about 2 area of study that includes Pengkalan Hulu and Gerik which located at the north of Peninsular of Malaysia. Pengkalan Hulu, a small town and near with the Thailand-Malaysia Border is located at 5°42'4"N 100°59'58"E while Gerik is located at 5° 25' 0 N 101° 7' 60 E. Gerik is a small area which also spread across 100 square kilometer area at the north of Perak and has population of 29604.
Figure 1: Area of study which retrieved from google earth
Few studies had done in this area because of the tin ore that can find around these areas which is hydrothermally deposited. The areas is transect area between Thailand and Malaysia and seventy percent of the transect area on the Malaysia side is geomorphologically mountainous terrains covered by thick tropical forest. Large rubber and palm oil plantation can be found around Pengkalan Hulu and Gerik as the topography seem to be flatter.
This field record will shows the observation that had been made at our study areas which are:
1) Sungai Alai2) Road 1
3) Road 2 4) Sungai Lembu Kasi5) Sungai Kledang

Carbonaceous Slate, Normal, 4X
1) Carbonaceous slate 1- We could see that there is a lot of of carbonaceous material or opaque minerals in these
sections. Besides that, these black minerals don’t show any extinction and birefringence.

2) Carbonaceous slate 2- Just about the same as carbonaceous slate 1 with many opaque minerals but the
extensiveness of their avaibility is less.- 346 153

3) Limestone
-This limestone might have undergone neomorphism due to the presence of euhedral shaped dolomite crystals. We could also safely say that it also has undergone pressure dissolution as stylolite are present in filled in inorganic matter and clay materials.

Phyllite, Cross polarised, 4X
4) Phyllite 1
-As the slate (majority of rocks) has undergone metamorphism into Phyllite they become more compact. As they are exposed to surface under lower temperature and pressure, they form much more fractures and are also prone to weathering due to the damp river environment thus explaining the abundant fractures in this section.

Phyllite 2, Normal, 4X
5) Phyllite 2
- Just like Phyllite 1, this section also has a lot of fractures but much darker opaque minerals. This might be due to the higher carbon content. Their fractures aren’t filled with any kind of minerals thus might be recently weathered. This also explains why they are easy to break.

Quartzite, Normal, 4X

6) Quartzite
- As the rock is entirely composed of quartz crystals being very hard thus we assume it to be a quartzite. The orange layer in the top picture is due to presence of iron oxide leached from the surrounding.

7) Siliceous slate 1
- Surprisingly the rocks of these sections are very hard and when hit creates sparks. Basically they characterize like normal slate but the distinguishing feature is the presence of quartz infilled inside their fracture. This makes these rocks much harder than normal.

9) Slate
- This section consists of very fine grains forming beautiful thin laminations which is indicative of slate.

10) Slaty slate
-The difference between carbonaceous slate and slaty slate is that the slaty slate has much less carbonaceous material. That being said, the amount of clay sized grains and fractures are also high.
