I think you might be referring to 伦敦金 which translates to London Gold or Gold in London、However, without more context, it's difficult to provide a more specific answer.

Could you please provide more information or clarify what you mean by 大陆伦敦金? Are you referring to:

1、Gold trading in London?
2、A specific type of gold product or investment?
3、Something else entirely?

I'll do my best to help once I have more context!
