Two laboratories analysed identical splits of samples from Lubbock Lake, Texas, without knowing their depths. Magnetic microspherules and nanodiamonds were low or absent at, above and below the boundary except in one sample younger than 11,500 years, where they were two to four orders of magnitude higher. **Younger Dryas impact hypothesis** Articledoi: **[10.1371/journal.pone.0155470](https://doi.org/10.1371/journal.pone.0155470)** Checked against the original0 ## What it's used for here A blind split-sample test of reproducibility and uniqueness. ## The document 13 pages [Pages][Text]Page 1 of 13 [![Page 1](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p1)1][![Page 2](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p2)2][![Page 3](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p3)3][![Page 4](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p4)4][![Page 5](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p5)5][![Page 6](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p6)6][![Page 7](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p7)7][![Page 8](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p8)8][![Page 9](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p9)9][![Page 10](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p10)10][![Page 11](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p11)11][![Page 12](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p12)12] ![Page 1 of A blind test of the Younger Dryas impact hypothesis](https://mysteriesdept.com/files/v/a629f5e14a115a856f215ac865537a5ccf15bf46c8733389e6386156ca399deb/p1) The first 12 pages are shown; the rest are in the file.
