3. 1)Inconsistent texture patterns codes for stratigraphic units 2)Legends of the 48 area sheets of Taiwan geological map published by CGS since 1980’s are inconsistent 3)To solve the problem, legends of area sheets covering each of four regions of Taiwan are consolidated. The four regions are the western Taiwan including Shueishan Mountain Range, Ridge Mountain and Igneous rocks, the southern Taiwan, the eastern Taiwan, offshore Islands 4)Pescadores (Penghu Islands) and Tananou complex in eastern Taiwan are not included in the legend consolidation because there are no problems in inconsistent legend 3

4. 4 Problems in CGS-published Area Sheets of Taiwan Geological Map 1.Same stratigraphic units are represented in different legends (texture patterns) 2.Contemporary stratigraphic units are represented in different legends (texture patterns) 3.Texture patterns of legends do not conform with lithology 4.Formats of legends are not consistent 5.The same stratigraphic unit has different names or codes on different area sheets 6.Different stratigraphic units have the same codes 7.The English name of a stratigraphic unit has different spellings
