Organized each year by the USRA (Universities Space Research Association) since 50 years, the Lunar and Planetary Science Conference gathers international specialists coming to Houston for presenting the latest results of their research in planetary science. The first one, known as the known as the Apollo 11 Lunar Science Conference, was held in Houston from January 5–8, 1970. It will be honored this year. Until 1978, presentations at the conference focused on the study of the samples returned from the moon. In 1978 and after, the scope enlarged to the whole Planetology field. The first two presentations on Rochechouart at the Lunar and Planetary Science Conference were given in 1980, dealing with the identification of the projectile. All together 17 presentations including 2 in 2019 deal with Rochechouart impact in this series of Conference.
The two presentations will take place Tuesday, March 19, 2019 in the
IMPACTS: TARGET EARTH I session

IMPACTS: TARGET EARTH SESSION PROGRAM
1:30 p.m. Montgomery Ballroom
Chairs: Sean Gulick and Anna Losiak
| Times | Authors | Abstract Title and Summary |
| 1:30 p.m. | Gulick S. P. S. * Christeson G. L. Morgan J. | Heterogeneity of Large Impact Structures as Illuminated by Chicxulub: A Terrestrial Analog While Placing IODP-ICDP Expedition 364 in Context [#1654] We discuss heterogeneities of the Chicxulub structure deposits and melt rocks placing IODP site M0077. Controls on such heterogeneities yield insights. |
| 1:45 p.m. | Huber M. S. * Kovaleva E. | Was the Vredefort Melt Sheet Similar Composition to the Sudbury Melt Sheet? [#2396] Big impacts make melt sheets / Does massive crustal melting generate similar compositions? / Modeling tells us it can. |
| 2:00 p.m. | Hill P. J. A. * Osinski G. R. Banerjee N. R. | Through the Impact Glass: Understanding the Origin and Evolution of Impact Melt from the Mistastin Lake Impact Structure [#1664] Through the impact glass / Mistastin Lake’s origin / A story revealed. |
| 2:15 p.m. | Jaret S. J. * King D. T. Jr Tailby N. D. Adams M. C. Ebel D. S. | Impact Melt Clasts from the Flynn Creek Impact Structure, Tennessee — Temperature Constraints from Titanium-in-Quartz Thermometry [#3170] High titanium / In quartz tells that it formed at / High temperature. |
| 2:30 p.m. | Pickersgill A. E. * Mark D. F. Lee M. R. Osinski G. R. | A Refined Age for the Gow Lake Impact Structure [#2375] Gow Lake age (million) / One hundred ninety-seven / Argh! Extra argon. |
| 2:45 p.m. | McGregor M. * McFarlane C. R. M. Spray J. G. | Multiphase U-Pb Geochronology and Shock Analysis of Apatite, Titanite, and Zircon from the La Moinerie Impact Structure, Canada [#2428] First higher precision age constraints on the La Moinerie impact crater, Canada using multiphase U-Pb geochronology on apatite, titanite, and zircon. |
| 3:00 p.m. | Lambert P. * Alwmark C. Baratoux D. Bouley S. Brack A. et al. | The Rochechouart 2017-Cores Rescaled: Major Features [#2005] Presenting and discussing the rescaled and correlated core/borehole wall observations for the cumulated 544 m cores recovered in the Rochechouart impact structure. |
| 3:15 p.m. | Ormö J. * Sturkell E. Lambert P. | Sedimentological Evidence for a Forceful Resurge at the Rochechouart Impact Crater, France: Implications for Target Environment [#1785] The SC2 core suevite deposits suggest a shallow marine target environment. It is important for cratering mechanics and paleoenvironmental reconstruction. |
| 3:30 p.m. | El Kerni H. * Chennaoui Aoudjehane H. Baratoux D. Kenkmann T. Wulf G. et al. | The Size and the Center of the Agoudal Impact Structure (Central High Atlas, Morocco) [#1331] In order to constrain the center and the size of Agoudal Crater, the natural neighbor interpolation technique and the Concentrc Deviation Method were used. |
| 3:45 p.m. | Losiak A. * Belcher C. Jõeleht A. Plado J. Szyszko M. | Death from Space: Origin of Charcoal Found in Proximal Ejecta Blanket of Kaali Craters (Is NOT What We Think) [#2406] Pieces of charcoal found in the proximal ejecta blanket of Kaali craters were most probably not formed by the radiative heat of the bolide. |
| 4:00 p.m. | Simpson S. L. * Osinski G. R. Longstaffe F. J. | Hydrothermal Clay Mineral Production in Meteorite Impacts: Lessons from δ2H and δ18O of Smectites from the Chicxulub Peak-Ring [#1663] Crater clays preserve / Isotopic memoirs of / Hot, strange histories. |
| 4:15 p.m. | Hildebrand A. R. * | The Highly Oblique Source Impact of the Australasian Tektite Strewn Field in Champasak Province, Laos [#3116] The Australasian tektite strewn field source impact is located in Champasak, Laos; this highly oblique impact produced a doublet of two elliptical craters. |
| 4:30 p.m. | Schultz P. H. * Harris R. S. Peroud S. Blanco N. Tomlinson A. J. et al. | Late Pleistocene Fireballs Over the Atacama Desert, Chile [#2893] A series of intense fireballs during the Late Pleistocene generated widespread glasses through radiative and convective heating. |
