), suggesting that RE elements can be divided into two groups with Gd as border. This phenomenon is called Gadolinium-broken effect. Key words: weathered crust; ore; rare earth partition; correlation analysis1...%, even up to 50% in some weathered crust ores such as Longnan ore. Y is regarded a heavy rare earth element because its properties and radium are similar to those of heavy ones, which is also supported......
