GEOLOGICAL CONTEMPORANEITY AS VIEWED FROM THE THEORY OF RELATIVITY

Since the importance of tho iron ore resources of the contact metamorphic type in China has been well recognized by many geologists and their geological occurrence and economic prospects have been described and published in detail 1, it seems desirable to have a review of those rocks known

書報述評

此書爲研究經濟地質及變質岩者所不可不讀,歐美各國對於火成岩之研究甚早,獨我國對於此類之研究殊屬罕見。此篇为著者等三年心血之結晶,關於野外之觀察以及室內顯微鏡下之研究與化學成分之分析均叙述精詳。凡所有岩石之分類,以倪格里氏為主,鑛物及產狀爲副。據研究所得岩石種類共三十     

科學方法之研討

Ⅰ 緒論任何適當的科學方法之研討,必論及两种科学行为:其最要者曰調查研究之法,亦即發現事實真相之途径;次日陳述之法,即以調查研究之結果,用語言或文字,使羣众認識之謂。因文字能達於多數羣來,故著述之方,较诸口授,更有實際的重要性。
