1. 三峽文石的野外產狀有杏仁狀及脈狀充填，多以球狀體的方式堆疊生長，常 有同心圓狀組織出現。五寮、詩朗及三民橋地區的文石多以氣孔填充的同心 圓為主，顏色較竹東文石鮮豔且對比強烈，竹東地區的文石則以礦物結晶良 好的脈狀填充為主，同心圓狀較為少見。
2. 文石的同心圓狀組織經由顯微鏡觀察發現可分為三種類型，第一為礦物顆粒 大小或礦物相上具有重覆性的生長，第二為礦物顆粒由同心圓中心向外逐漸 增大，最後一種為孔隙經光線折射所形成的同心圓條帶。
3. 本研究檢測出三峽文石礦物有方解石、菱鐵礦、白雲石、鐵白雲石、石英、
玉髓、蛋白石、綠泥石、赤鐵礦及黃鐵礦等，碳酸鹽類及矽酸鹽類礦物為主 要文石礦物，其中以方解石佔總數一半以上。五寮地區以方解石數量最多，
詩朗地區除了方解石，另發現較多的二氧化矽礦物，三民橋地區出現方解石、
白雲石，竹東地區則以方解石與含鐵氧化物為主，其中較特別的是發現有細 粒的黃鐵礦沉澱在孔隙邊緣。
4. 三峽文石化學成分主要由鈣、鎂、鐵之碳酸鹽類組成，鐵離子含量越多，文 石的顏色越深。五寮、詩朗及三民橋地區的方解石及菱鐵礦含鎂量較竹東地 區高，其中三民橋地區文石礦物的整體含鎂量為四個地區最高，另外詩朗地 區含矽量特別高，竹東地區的方解石鈣含量及菱鐵礦的鐵含量都較其他地區 高。
5. 三峽文石碳氧同位素中，δ13C 為-2.7〜+4.5 ‰，δ18O 為+20.9〜+25.6 ‰，碳 同位素顯示溶液來源可能以海水為主，並混和少量淡水，利用氧同位素以海 水來源推算成礦溫度，約為 40℃。而在同一件樣本中，核心與外環數值相近，

暗示著同一顆文石的不同同心圓條帶，其生成的溶液來源接近，或可能為同 時期生長。
6. 同心圓狀的文石為成礦溶液在孔隙邊緣開始沉澱，偶會在孔隙壁先形成薄層 的二氧化矽、氧化鐵或黏土礦物，之後在上面形成許多的晶核，最後再包覆 著這些晶核逐漸向孔隙中央充填其他的礦物，形成複合式同心圓或連珠狀文 石，另有由樹枝狀鐵或錳氧化物與碳酸鹽類礦物共同生長的樹枝狀文石。
7. 三峽文石與澎湖文石相似，但目前三峽文石仍未發現沸石類礦物及菱鎂礦。
三峽文石的化學成分則較澎湖文石的鎂、矽含量高，可能為三峽文石的富鎂 成礦溶液與富矽的沉積岩交互作用所致。以碳氧同位素來看，三峽方解石生 成環境以海水為主，並混和部分淡水，不同於澎湖方解石的主要形成環境為 淡水來源。
